Severe and strange battery issues - Please help!

Hello, I've recieved my AT&T Tilt 8925 (Kais100) unit a week ago and ever since I've experienced awful battery performance. The item shipped new (not refurbished supposedly nor defective) and included a Samsung battery. I changed to Dutty's v3 ROM right away (flashing was successful, I also switched to radio version 1.27.12.27) and last night switched to Q-Mobile v1.2 to see if the ROM was the problem, but it persisted.
My battery drains extremely fast, even when the unit is off it drops 10% after 8 hours (overnight and also throughout the day, I'm leaving the unit at home while I solve this issue and it's always off). The unit does not have a SIM card inserted and the Phone function remains off, so does WiFi, Bluetooth, Beam, 3G, etc. It's also muted and has no alarms activated, nor background programs running (I'm currently running a freshly flashed Q-Mobile v1.2 ROM with a hard reset done as well).
I've read about battery perfomance extensively but haven't ever read about the battery discharging while the unit is off, and given the fact that I'm NOT using the phone functions, I barely believe this can be normal behaviour. I purchased 2 units from the same source and both are having similar issues with battery perfomance.
I'm currently testing a borrowed OEM Dynapack battery from a friend's Tilt to see if it shows the same behaviour as well to discard the possibility of a faulty unit. Note that I'm using the OEM 1A charger and leave the unit charging for several hours.
If the battery proves to be defective I'd have to get one (or contact the seller to see if he'd respond to the issue). Can someone recommend a cheap/reliable battery that could be bought online (eBay, etc.)?
Thank you very much! I hope that someone has a clue on this issue.
Best regards
Sebastian

Just to clarify, is the phone actually OFF, or is it in standby? If it's in standby, 10% after 8 hours wouldn't be unreasonable at all.

Uhm, it's on standby I guess (when I turn it on again it's instantaneous, not like when you soft reset the unit)...

I'm new to PDA phones, I had an IPAQ RX3715 before with WM2003SE and I could leave the unit off for days without battery drainage. However I may not be too familiarised with these new units' standby/off functioning. If in standby and with the Phone function off (meaning that the device has "nothing to do" other than being off) it's normal for the device to drain the battery so much I would be disappointed.
As a sidenote, my friend's Tilt is not draining while it's on standby being on the same conditions other than the fact that his unit has the Dynapack battery.
Regards!

Bat Drain
I have the same rom and the same problem. I was at the hospital all day i made two calls and about mid day my bat was at 30%. I think its duttys rom V3 causing the problems. Changing roms now.

I could be wrong, but I think your phone is fine, these devices just consume a lot of power. 10% over 8 hours would be totally normal in my opinion. Is that the main reason that leads you to think there is a problem with your phone? Have you ever had a pocket PC before that had better battery life? When I got my first PDA I thought the same thing, but I realized that they are not like normal cell phones, where you could just recharge once every couple of days. PDA's must be charged at least every night. If you use GPS or wi-fi a lot you're probably going to be charging sometime throughout the day as well. I just got into the habit of plugging it in every time I get into the car, and when I get home I plug it into either the computer or the wall charger. There are after market batteries available, but if you want a drastic increase in amp-hours, the battery is going to be bigger and it will require a new battery cover. This is totally unacceptable in my opinion, as the device is relatively large to begin with. My advice would be to only activate a radio if you are using it, and de-activate it when you are done. Also just get into a routine where you are charging it whenever possible. Another thing, I just flashed Dutty's V4 RTM, and I must say the increase in battery life was very noticeable. Don't let me confuse you, though. From the information you supplied, I really am not able to tell if there is a problem or not, so give some more information and examples of battery life so we can figure out if somethings wrong, or if you just aren't used to the amount of consumption of this type of device. Hope I could help. Cheers!

Yeah that's not normal. You got any radios besides phone running throughout the day?

Thanks for your thorough reply. Picking on what you mentioned, it's true that I'm new to PDA Phones, as I mentioned I also own an iPAQ rx3715 with WM2003SE and my idea was to replace it. Judging the fact that PDA-only devices, to my eyes, are nowadays dying I thought I'd get me the latest and most complete device available WITH GPS, since I was using my iPAQ together with a GPS Bluetooth Receiver with much delight.
What I experienced with my previous device was that battery performance was never an issue, it did consume power as any PDA, but I didn't find myself worrying about it, it never dropped when off and it would last me several days.
Since I'm using my Tilt with the Phone function off I _thought_ it wouldn't need any power for anything... but it might be that these new devices, or the new WM6 architecture is different to that of WM2003SE/PDA only devices... I don't know, but it just sounds strange to me, although if it's normal I'll live with it- as you say, I'll have to be charging it 1-2 times a day.
On the one hand it would be good for me to know that my device is ok, but on the other hand it means that battery life isn't even close to what I expected... I had read people complaining about it but in general I tend not to be overly critic about the defects of devices... but it seems that it's the case. I meant not to use the phone features and thus I thought it wouldn't be consuming power on standby seeing that the phone should not be running anything on background...
Thank you again for your reply. If anybody else has a word on this I'd appreciate it.
Best regards

Just as an aside you will notice the battery life getting better after a couple weeks it seems the battery has to be conditioned so to speak. Also do you have any kind of push email on your phone as if you do that does use quite a bit of power, you might want to set it up as a pop3 account and set it to check emails every so often instead of getting them as soon as they come in.But I have amde it a habit to always use my charger whenever I am able to as these batteries seem to be happiest when topped off whenever possible.

Hello again, I'm still experiencing this problem and it seems not normal.
Simply put, I fully charge the device. I turn it off. It discharges by itself with all wireless functions off.
Today I did a hard suspend (keeping off pressed) with battery at 60%... when I turn the unit on 7 hours later the battery was at 6% with a critical warning sign.
I'm NOT using the device, I turn it on, use WiFI for 3-5 minutes then switch it off and put the device to suspend. I turn it on after a couple of hours, play with the menus and turn it off again. Just by doing that the battery drains by 10% every 5 hours or so, sometimes it won't even turn on due to battery drainage.
Is this NORMAL? I need to know if my unit or my battery is defective so I can return it to the seller in time...
Thanks, best regards
Sebastian

Battery life DOES seem to improve with time. The first day my battery wouldn't last for 5 hours! Keep charging your battery and letting it drain as much as you can (whether or not to let it fully drain is debatable), and I bet you'll see some guaranteed performance.
Also, what would help a lot is if you found and installed the Today plugin BatteryStatus and checked the "Show More indicators" option, and see what your battery drain was. The normal is between 150mA and 300mA when you're on the Today screen. Any more than that, and you most likely have a problem, assuming connections besides phone are off.

sounds normal to me, turning off you mean by pressing the button on the right side of unit? if so, mine is the same way

I'd say that was definitely not normal performance. On average, I use mine for at least an hour worth of talk time, an hour or two running TomTom, numerous SMSs, and at least a couple of hours reading books. I charge it every night, and the battery is generally running at around 50 to 60% by that time. I'm surprised at how quickly yours is draining.
I have an RX3715 inhabiting a drawer, and, while the battery life was a lot longer on that device, the battery was a lot larger, and the screen lower quality. The fact that it is not connected to a mobile network gives the battery a much longer life too. When I used it purely for TomTom, connecting to a bluetooth receiver, the battery faded very fast.

I've had a Kaiser since day one. I have found that adding a comm manager that allows forcing the phone to Edge give huge battery savings. In standby with the phone radio On and BT radio ON, WiFi OFF, my phone drops 4% over night very consistant. On Edge battery lasts days.
The only time I get fairly high battery consumption is streaming with 3G. Edge is so much more efficient on the battery, so if you don't need the speed, throttle down!
The only time I've ever found the phone Dead or close to dead after only a few hours on standby was when I had WiFi ON and the phone in standby. I can't pinpoint what exactly causes the condition, but when it occurs, the phone is HOT and the battery heavily drained in a short time. This has happened with both Hermes and Kaiser. I never leave WiFi ON when not needed, and have never seen severe battery drain since.
I do sometimes turn off all radios except WiFi, and then use wired ear buds and stream Slingbox video to the phone over my home WiFi LAN. I can get almost 4 hours of watching on a charge.

The battery should not be draining when powered off, but not much at all when put in sleep mode. Get yourself a replacement Testing.
As an aside, Alex's WM 6.1 BETA 2 has given me the best battery life of any rom. Only about 25% of the battery drains per day. With most other roms it's 50-100% per day.

Hello, thanks to everyone for your replies. It's strange because I've been doing lots of test, switching batteries (I have 4 units to test now) and I get inconsistent results... the 2 most problematic units were bought from the same eBay seller and got their ROMs changed the first day, the 3rd unit still has the AT&T ROM and was apparently not draining as fast. The problem is that the 2 first units seem to get battery drains overnight in flight mode of 10% and 2 times one of them got a 0% critical battery status just by being in standby and not in use (none of them are working as phones and have the function off)
The odd part is that for some reason this happens only sometimes, now I've switched to Sleuth's WM6.1 ROM and the problem is gone for now, I'm still at 90% since 2 nights ago having turned on GPS and WIFI for 5 minutes each 2-3 times... the other 2 units have been in standby from 100% charge and they haven't dropped either! And they're using the AT&T ROM and Q-Mobile v1.2 respectively... what kills me is that I cannot say what's wrong, cause I've swapped batteries, swapped chargers, swapped ROMs but cannot trace which is the problem (or if there's a problem at all)...
Perhaps it's normal for the unit to sometimes drain 10% after 8 hours of standby in flight mode and on other times remain at 90% for 2-3 days if not in use...
Thanks everyone for the read, I'd appreciate any comments
Regards
Sebastian

What radios are u using. Try changing radios

10% loss overnight in standby would be normal.
Does the unit get warm when you notice rapid drain?
I wonder about the "old" active sync problem - does the device show any running programs when you turn on?
In general you should expect to get a days worth of power using it for the odd call, perhaps an hour of wifi and perhaps an hour of prgram use. Of course all taht is very variable but I generally get away with a charge once a day. Occasionally, I take it from it's holder and it's warm to touch, but usually it's 'cos I've forgotten and left something like tomtom running.

Is Battery life really short?

Hi Everybody,
I am using my HD2 since 2months and I share with you the general Idea that Battery life of 1-2 days is not enough for a device with the ambition to serve as phone as well.
I am using the device for professional activities: document sharing, webcalendars, emails on the go... but with an internet access not contiguous, since I only want my mobile to donwload mails when I
am not at home or in my office (were I have more professional stuffs
for that).
So, I installed the WMLongLife to Switch off communication interfaces whenever not used.
However, during last couple of weeks it happen to me to work prevalently at home and in my office, without the requirement to use the network from my HD2.
Accidentally I noticed that if I charge the HD2 and never use internet services (but only as a phone: 5-10 calls per day), the battery life magically goes from 1-2 days to 1 Week and more.
Is it normal? Maybe some device is not properly shut down after first use?
Now I charged my mobile on thrsday morning, and after 5 days of use I have still 42% left.
I wish to share your opinion, and to know if there is outside a better software than WMLongLife to preserve batteries when high speed connections, BT and Wifi are not used.
Thanks a lot

It's a phone with a massive screen, bluetooth, wifi, 3G and the list could go on...
I myself, is amazed that it can last a day.
Using it with constant 3G, bluetooth, GPS back and forth at least once a day, e-mails ticking in all the time, bluetooth headset and so forth...
The HD2 is like a small laptop...
- try getting a laptop run a full day on a battery the size of the HD2s.

1 week and more? Wow....

I fully charged the phone last night around 12AM, now after 13 hours most of which is standby, 1 hour of music, and maybe 30 minutes of browsing/playing with it its at 70% battery life. Is this normal?
I dont get 3G and I have wifi and bt off. Any other ideas to conserve battery?

The HD2 is as good, if not better than any other smartphone I've owned. I always recharge my phone overnight, so as long as the battery's good for a day I'm happy. Any bigger battery and the phone would need to be much fatter to accommodate it.
A week sounds pretty optimistic to me.

You could try and turn down the brightness of the screen for one...
I had mine on 100% for the first couple of days, but it just ate the battery like that. Then changed it to 70% (almost can't see the difference) when it's on battery, and that helped a lot!
Then you should perhaps try and download BsBTweaks or something like that, and activate the "power save" option...
Something to do with the SD card or something, not sure...!?
But to be honest, I think it's pretty decent.
13 hours of stand by, 1 hour of playing music and 30 minutes browsing/gaming - and still on 70%.
You have to remember, it's a very powerful device and as such it uses a lot of power!

Again I confirm,
charge this morning is still 25% left and yesterday I used internet connection for 15 minutes, then switch off devices and a soft reset to stop eventually pending drivers.
I do not use HD2 for listening music or playing films: only calls, contacts, synchronized agenda with gcalendar, emails, and internet.
Previously I noticed that after using even once the internet connection (without the soft reset), battery last at most 36 hours.
That is why I suspect some processes/services be pending in background and draining battery low.

Again I am not trying to demonstrate the life of my mobile is longer...
... Just noticed that there are some operational conditions that may prevent higher power drains and to understand if someone else has investigated the point.

I do the same!
Check email one or twice a day. 5/6 calls a day. Wmlong life on. Don't care about 3g... it's set to be in automatic. Some excel and word files. Some sms. It's incredible that such a powerful device can stand by so long!
Otherwise when I use it for work, wi-fi, bluetooth, gps and bla bla, the life of the battery is about 12 hours... but who cares?

9% this morning but still alive with phone interface working...
Do it exists for WM6.5 an extended taskmanager (AKA in the windows style) that can also reports for processes and spent CPU time?

I can barely go a full day and have to charge it at night.
Is anyone else getting really poor battery life? I have Wi-Fi on a lot but with screen off just so it automatically gets my push e-mails. Could this be the reason?

[Q] Am I the only one getting good battery life on this phone?

Before I bought the Vivid, I read every review that was out, even the customer reviews on AT&T's site. There was a common theme in all of them: Battery life is bad. Even the glowing reviews had "battery life" as a con or said they wished it was better.
Needless to say, my expectations weren't high. I have had HTC phones in the past and battery has never been their strong suit.
Imaging my surprise when I tell you that after a 10 hour work day, I go home with an average of 60% battery. I text throughout the day, have seven e-mail accounts syncing, widgets that pull data on my home screen, etc. I am definitely using the phone. I leave Wifi on all the time and I have LTE access wherever I go, so the LTE radio is always on.
Am I really that unique? Is anyone else getting good battery life with the Vivid? If the Skyrocket is supposed to have way better battery life, I can't imagine how long it would last compared to my Vivid, at least with my use.
Overall, very happy with this phone. Battery life is what always drove me away from Android and that is not an issue here.

I would say I unplug my phone around 7 and it gets to 10% around 7 so 12 hours ? I would say thats pretty good battery life I came from the inspire and it would die after 7-10 hours so I would say its a lot better! Though I cant wait for a cm9 or 7 rom since i was getting a full 24 hours + With that.... So im very excited to see!

I am also getting about 10 hours with heavy texting use throughout the day. I have friends overseas and we text via Whatsapp and sometimes Skype. Otherwise it would last even longer since I the screen display wouldn't always be on. I am not complaining getting 10 hours of use though since I'm coming from an HTC Aria which was about half that.

Almost as good
With the standard battery that came with the Vivid, I am getting 24-48 hours on a charge, but I don't use it as much as described above. I have WiFi on at work, but I don't do a lot of e-mailing from the phone. (I work at a desk all day, so I have e-mail on my PC.) But I do look up a lot of things. I suspect I use the phone for at least a few minutes 6-8 times during the work day and 2-3 times in the evening (with WiFi at home). I am not a heavy data plan user, partly because of WiFi access. I use Bluetooth to connect to my car's sound system during my 30-minute commutes. I usually put it into Airplane mode at night, cutting down on the battery consumption. So, I would expect to get somewhat better battery usage than someone who is on their phone much of the time.

Just out of curiosity: Why put it in airplane mode at night? Why not just plug it in to recharge?
I have a lot of days like you where I use it lightly. I have noticed that the idle drain on this phone isn't nearly as bad as past Android phones I have owned.

Yesterday I got 16 hours out of my phone. That is with me syncing three email accounts, running a live background, using data to read news articles, downloads from the android store, browsing the web, and making around 30 minutes of calls. It is much better than my cappy was. I made sure to charge the battery when I first got it all of the way before powering it on. I also have let it run down completely to cycle the battery.

When my phone was stock the battery life was OK, not terrible, but not great either. With a custom ROM the battery life has increased greatly. I unplug it around 8am and when I go to charge it at night I usually have around 40% left. That is with moderate to heavy use, at least that's what I consider my use.

Failed to mention I am on the stock Rom.
Sent from my HTC PH39100 using XDA App

I got around 17 hours last night and was only down to 70% left. Quite a bit of use too. It's actually better for me than my GS2 was.
Sent from my HTC PH39100 using xda premium

I'm always getting 20+ hrs on my vivid with med. Use with the stock Rom my battery was pretty good but with rumraider its going on about 30 hrs with 40% left ....wow and I haven't even charged it since I flashed

I think alot of the differences in battery life have to do with how strong of a cell signal you have. The weaker the signal, the quicker the battery dies since your phone is constantly trying to stay connected. Also, if your signal is bad, than that usually means your internet data is slower too and thus it takes longer to download news, email, and web pages, thus killing your battery even further.
Although, my signal is usually at 2-3 bars, the battery seems to last much longer than I was led to believe from reading reviews. Overall, I am pretty happy with this phone.

Just a suggestion, I am getting fairly good battery left, I am on a rooted stock rom with most of the bloat ware & processes frozen thru Ti Backup, I have wifi on all day but limit sync schedule (with refresh on use enabled) I have noticed that the battery stays at 100% for a while then starts to drop off. Today running about 7.5 hours and currently have 95% charge available. I also have Juice Defender free helping out with ballanced profile enabled.
Cheers

Simple rundown:
I text fairly frequently, do a reasonable amount of web browsing (read: where I don't have access to a computer), sync 3 email accounts, check XDA and play GameBoy on the thing. Weather is on hourly autoupdate with location; news is on demand when the widget is viewed.
The only daytime charging I do is when I'm using my phone as my car's AUX input, where it is plugged on the charger (although still draining according to the battery graph).
I end the day with 52% battery life, off the charger at 7:45 AM, back on at 12:00 AM. Much better than my Captivate. Prior to root, custom ROMs and SetCPU, it would clock in at around 38%.

I totally agree with this. My office is in the basement of our building and I get fairly poor signal - maybe 1 bar but I still can access the LTE network. When I turn my wifi on, by the end of the work day, my battery is much less drained vs not having it on and my phone searching for signal from the mobile data network.
At home, I have a pretty good signal, but there's not LTE coverage yet, so the battery does last longer throughout the day.
Even on the bad days I would get home and keep it running until I plug it in before I go to bed, so that's an average of about 17 hours in total per day that it's running on battery and on average I'd have like 30-40% battery left.

I was using an iPhone 4s before I bought the Vivid and I used to go home with about the same amount of battery after a full work day. Granted, the 4s gets worse battery life than the 4 by far, but I still think it's impressive that an Android phone, especially an HTC does this well and it makes me wonder why all of these people in the reviews have been getting such bad battery life.

It all depends on what it's relative to. When I had a BB, I'd go almost 5 days between charges, but there's no comparison between a BB and a 4.5" LCD screen.

This is a key point. The big screen is a huge battery sink. The battery widget in Beautiful Widgets gives a percentage battery use for components. With mine, the display's battery usage is always at least twice as big the next nearest battery sink. It is not uncommon to see that it is using 90% of the juice. I think this explains a lot of the early complaints about battery life. We all spend hours playing with a new phone and getting it set up to our liking. That means the display is lit up for hours. That means people get lousy battery life when they first get their phone.

I was trying to see how long I could go on a single charge. Airplane mode shut down radios that might otherwise continue to run, trying to pull data I would not see while asleep. Also, I would occasionally run the battery all the way down before recharging. I generally plug it in at work, in my car or at home when it gets down around 10% remaining.

Battery Life

I can't believe how incredible the battery life is on my Sprint Note 4. To give you a real world example of what I'm talking about...I'm a ups guy and stream Sirius over my phone to my wireless boombox all day while I'm delivering. My previous android phone on a full charge would get me to about 1PM before needing to charge the phone from this streaming.
With my Note 4 today I started streaming sirius at about 8:30am this morning and streamed it non stop all day for 10 hours. While streaming I also browsed the internet on lunch for about 40 minutes of screen on time for that. I then made about 40 minutes of phone calls after work on the way home. After all of that...I still have 60% battery life left without any charging today.
Man I love this phone!

tried ultra battery saver mode for the first few days and made it from 100% to 25% in 2 days and 4 hours with ultra on and off. then played a game for about 7 hours and it drained my battery 50%. Damn impressive

Not sure what to make of mine, I lost 10% in an hour, most of that was when I was driving!
Hmmm, but then I do seem to have a lag issue like others seem to be having too?

It's either something you have installed or how you have your preferences set. I turn off wifi & gps except when I'm using them (both for battery and privacy purposes).

With my Note 4 today I started streaming sirius at about 8:30am this morning and streamed it non stop all day for 10 hours. While streaming I also browsed the internet on lunch for about 40 minutes of screen on time for that. I then made about 40 minutes of phone calls after work on the way home. After all of that...I still have 60% battery life left without any charging today.
Man I love this phone!

I simply can't agree more dude the batt life on this beast is simply incredible I'm averaging around 13-15hours off charge with 6-7hours On Screen, take note (pun intended ) that when I put it on charge when I go to bed I still have well over 25% battery remaining, its simply incredible, even for us heavy users.

Must have a lemon
I have had my phone for about 3 days and I charge it to 100% before going to bed. When I wake up the battery life has dropped all the way into the 60s. before this phone I had a note 2 and this is way worse than it was. Screen was obviously off all night. Any suggestions appreciated!

It all depends on what you have running in the background. Push notifications? I've frozen all bloatware and turned off push. Is your wifi on maybe? gps? I leave mine unplugged all night (12 hours) and it goes down 3%

Did you install anything special like Greenify? Did you use any of the extra battery saving modes? What is your screen brightness set to?
I think the Sprint version is the Snapdragon, not Exynos, right?

I absolutely loved my Note 2 battery life, but this Note 4 battery life surpasses my Note 2 by a fair margin. I am one happy camper.
Edit: Sprint SD version.

I'm getting less battery life than I expected with my Exynos note 4. I just got out of bed and unplugged it , and used it for about 15 mins to browse tapatalk and email and etc. And in that 15 mins I lost 5% .

I also noticed a high Android System in my usage. Any thoughts on what could be causing this?

This is screen cap.

Mine today

Im only plugging in now at 24% because im going to bed.... actually i have a second battery i might let it run overnight

Pretty good

If you have battery issues, make sure you are not syncing to drop box or google photo back up all times. For example, I use photos to back up all my photos but in the settings I have it only back up when plugged in to the charger. Hopefully this might help someone.

Nothing special installed for battery life and not using the power saving modes. I keep the screen set to auto brightness when at work, but put it on max brightness at home on the weekends when I know I have chargers available because I love the nice bright display. Yes, I have Sprint which has the Snapdragon 805.
I turn off GPS & Wifi when I'm working for battery saving & privacy purposes, but leave bluetooth on all day. I don't have my microsoft email auto synced, but have gmail pushed.
Here are the results from today (attached). Still well over half a battery left after midnight.

To all the people with battery woes-
Pause your pedometer in s health and remove pedometer from lock screen(of course if you don't use it much). It saves a hell lot of battery. It did at least on my SD805 note 4.. I am a heavy user with 3g on all day but never run out of juice. Screen on time averages 7-8 hours daily with browsing/playing games/chatting. I have wifi, synch and gps off when i am not using them.
And yeah i charge every morning, but have never seen my battery less than 39% when i charge lol. This beast is incredible. *super satisfied*

Battery Life experiences

Just curious on people's battery life experiences so far. This seems to be the main negative I hear about this device from reviews. I am most likely going to get the device nonetheless.

I don't feel like the battery life is that bad on this device.
I can get through a hole day very easily. I play some games (but not that much), I listen to a lot of music and I use Chrome very often.
Still I have about 40% at the end of the day.
For a device with a 1440*2560 5.7 inch screen and a Snapdragon 810 I reckon that it is pretty good.
I can only tell you to get this device it is awesome

Battery life for me is pretty terrible. The battery drain is significant even when the phone is in idle. I usually have access to a charger throughout the course of a day and I feel the need to keep it connected as often as possible. I still love the phone, but the battery life is the worst I have experienced with any phone I have had in the last couple of years, and I have used many. I leave it on balanced mode for the majority of the day and only switch to performance mode when I am going to play a graphic intensive game.

Yikes. Have you tried any software like Greenify to help alleviate the problem or it still persists ?

No, I haven't tried any apps or other battery profiles. Like I said, I keep it plugged in a lot during the day, so I have never felt the need to see how far I could stretch a single charge. This is also the way I have kept all of my previous phones and the Xiaomi drains the battery the fastest in comparison.

Mine lasts me about 12hours. I listen to music most of the day and I'm a heavy user.

Got the phone 2 days ago. got around 4 hours 15 minutes SOT from 7am till 9pm on the international rom. Better than i was expecting. Hopefully I can improve it further.

I have to admit that over time the battery got worse. That would be because I have more apps etc..

What is your SOT time usually?

I noticed today my battery SOT and idle drain has been really bad. The only thing I think I did diffrently was that I logged onto my miui account last night so i could download themes. I have no use for the miui account other htan the themes so I will try logging out and seeing how things are after it....

2-9% per hour is not bad i guess...
If i use it a lot, then only it will go as far as 11% per hour and mostly because the big QHD screen,
When it sleep, it almost didnt drain...
Of course you have to kill/disable all those stupid google play services... Named it Event Log and Checkin handoff etc etc
