Sooo. I have had my Optimus 2X for 2 days now. I charged the phone fullt before goint to bed and left wifi on. (should turn off when phone sleeps)
The first night i lost about 3% of the battery. Great....
But... The second night i lost 42%!!!
I have been trying to investigate the issue and after some digging with spare parts i found out the wifi was on all the time the second night... Also for some reason car home allways runs in the background (starts at boot and restarts if killed) and spare parts claims car home uses the phone sensors 100% of the time.
Anyone else having battery draining issues?
Im going to charge 100% again tonight and run with no installed user apps. If the problem persists i try and freez some of the loads of sys apps that run in the background all the time.
I also noticed some battery drain on mine but not over 40%... its more like 20%. The battery really disappoints me anyway. I have to recharge two or three times a day?l maybe thr battery needs to get trained over time, I hope...
You found a solution yet?

My battery already holds up alot better now, then when i got the phone four days ago.
About 60-70% left after a 14 hour day with some surfing, benching and calling/texting. Much better then my Desire on stock ROM, but still nowhere near the Desire on custom ROM.
Looking forward to some community goodness
BTW, removing carhome.apk seems to make quite the difference.

That's good to hear. Is it common for batteries to act this way? Talk about wildin' out.

In case anyone's interested what "carhome.apk" does, Google explains it here.
With mine no problem, wifi actived, all the night it's abourt a few %
I nerver seen that on my olders android phones
Great battery
Battery seems the get better every day.

Quick question about best used on the battery ...
Should we dry the battery to 0 for the first cycle ?
Or only to 20% ?
Is it bad if we start to charge the phone whent the battery is at 60% ?
On the contrary:
modern Li-Ion batteries don't like it if you discharge them to a minimum. Moreover they don't have the memory effect that you seem concerned about.
In a nutshell: Charge your phone whenever you can, at any charge level. Your battery will thank you.
On the first few charges though, you should always charge to 100% to help the battery gain her full efficiency
hey thx about those informations
but then i'm concerned about people saying stuff like "have been doing 3 life circle" for me it does mean they put the battery dry clean ...
Went to bed with 64% charge on the battery. When I woke up (8 hours later), still 64%.

What's your usage like?
Hmm... My phone last for 6 hours before drained... Had it for a week now... Takes about 2 hours to fully charge up again..
I even hardreset, turned of wifi etc... but alas, 6 hours and it was out of power again...
And that was just by being in standby.
If I actually use the phone, I can see the percentages going down from 100 - 0 in no time..

7 am: Full charged
After 2 hours of 3g, 5 hours of wifi, heavy texting, 30 mins of call, 30 mins of games
7pm: still has 36%
Not bad for an android phone.

Gonna try getting a new battery tomorrow... Hopefully it isnt the phone that is faulty...
2:nd day in my phone lasted about 5.5 h before I hade to recharge. Turned off the option for applications to sync and 20 hours later im at 32%
Hi guys. What are your ways, tips and suggestions for charging your z1?. Do you drain it completely and charge it fully afterwards? Or your the type of guy who partially charge and discharge often? And whats the best way to do the charging?. Thanks!

Okay thanks for the info!. My battery is not good. Its only 3day old and it drains very quickly. I never imagine how it drain so fast because its a 3000mah battery.

Normally it drain fast if you are playing games or browsing internet
due to it's 1080p screen,battery will be drained more fast.

I think the battery has overcharging protection, so it won't overcharge and damage it, so leaving it on charger during night, even if the battery reaches full level, is not going to cause harm.
Also, using the phone while it's charging, won't damage the battery.
Useful battery info HERE.
Thanks! I thought may battery is bad. 43% in 3hours the screen was on. XD
Best way to charge:
Quoting from http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries:
Code:
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
Charge at a moderate temperature. Do not charge below freezing.
Lithium-ion does not need to be fully charged; a partial charge is better.
Chargers use different methods for “ready” indication.
The light signal may not always indicate a full charge.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again.
Discard pack if the voltage does not rise to a normal level within a minute while on boost.

My N6 is about 12 months old since purchase. At the moment I'm using another phone as my main phone. I've noticed that the N6 battery percentage drops by 10% or more per day when it's sitting on the desk powered off.
This sounds to me like the battery has a serious problem. Any opinions or advice welcome.

Evert battery discharges itself. Only with 'trickelcharge' the self discharging can be stopped.
Perfectly normal for any battery.
http://batteryuniversity.com/learn/article/elevating_self_discharge
Yrs that's less than half a percent per hour. You might improve it by going to airplane mode and checking doze related sings, but it's already pretty low.

No it's not. From the page you linked: Lithium-ion 5% in 24h, then 1–2% per month (plus 3% for safety circuit)
Mine is discharging 10% or more per day until flat and if left sitting will fully self discharge in a week or so.

your battery will still lose power over time, then completely drain. my n7 2012 tablet dies every month, because i dont use it(powered off), then ill just charge it back up and not use it :angel:

Yes, I fully understand that, but it's highly unusual for a battery to self discharge in a week.
Hi all,
I having issue with my note 9, and I’m new to using note, is a 4% drain normal? Unplug at 12am and not use since and this morning I check battery was at 96% at 6.45am
How long have you had it. It takes some time for it to do battery optimizations but that drain doesn't seem too bad.
tat is only my 2nd or 3rd charge, have it only for 2 or 3 day
I have been draining about .7% an hour since I got it. I wish it was little bit better but the SOT more than makes up for it.
Sorry, but what is SOT? Screen on time?
So now on android ppl use SOT to measure if a battery usage is normal?

i usually get 1/2% overnight but when i had outlook installed i was loosing about 20% could be a app but 4 percent isnt something i would be concerned with... do you have AOD enabled?

AOD = OFF

I have the same issue
I have snapdragon n9600ss first I have enabled AOD and sleep like 2 am and wakeup 8 am check and 90%
I disable AOD and now have 94%
It's the same percentage I have with my old s9 but with AOD so I don't really happy with battery
I will wait 2 weeks and see if get better

Wow I'm telling you some of you people have some really unrealistic expectations. Your complaining your phone looses a few percent in 6-8 hours. What do you expect? If you don't want your battery to drain then turn off your phone or plug it in. And then don't come complain you miss calls or have to have it plugged in all the time becusse your worried about a few percent while you sleep.
YoshiYino said:

Preferable to not leave it plugged in at night if you want to lessen the longevity of your battery.
~.7% an hour is not bad. With root and older phones I was able to lessen to 2-3% per 7-8h. Ideally that is what you want, less than .5% an hour. But we don't have root. Other ways to get less drain at night during sleep is to turn off sync or airplane mode or better yet turn your phone off. But as I said .7% an hour is all day for me in standby. I don't even know what it is at night, probably less.
I've been getting well over 10h SOT and had another hour or two of SOT left should I have chosen to drain down to <5% battery. I have been able to get 8h+ SOT over 36h on a charge. Your expectations are unrealistic as are many others on here. Be realistic or get another phone.

That's interesting has to be a app causing the drain what third party apps do you have installed? the screen res wouldn't affect anything in terms of battery life because the screen is off. I charged last night and I'm at 16 percent right now on WQHD almost been 22hrs since I charged my phone

10hrs of SOT? That's crazy I think 6 was the most but this battery definitely gets the job done for me

Change the resolution to WQHD+, the power saving is too little to worth the downgrade of screen quality. Tested on s7e,s8+ and s9+ and read about it for note 9.
Also worth to note that iphones tend to show less drain at high percentages and then speed up after below 60%, i.e. if you leave the iphone over night with 30% battery, most likely it will drop 1-2%. Still, iphones standby is a little bit better vs android and samsungs. I achieved 1% drop over night or non in M8 android 4.4 times, not since them. My best is around 0.3%/h via root and custom tweaking, for samsung stock it's normal to have 0.4-1%/h. Hope that brings some clarity.

How do i see what apps is draining the battery?
It's not an original battery that i bought.
First charge.
Assuming that it hasn't been used before, is this normal?
Are stats going to change after a few charges or should I delete battery stats to refresh... ?
I don't have much knowledge about these stuff.
Probably I've just been given a used battery, but I gotta ask anyway.
What your SOT look like?
If new there should a huge improvement.
Battery calibration may be off...

SOT is almost the same - 4 hours approx.
I'll check batt. calibration..
I'll calibrate battery, charging full and deleting batterystats, to see if there will be any change.
