Hi all,
I noticed that LG Optimus 2x has the lowest display battery consumption percentage I have ever seen on any Android device. Independent from the ROM I use, I usually get between 3 and 10 (very rarely!) percent in the battery stats. All other devices I have seen until now usually have the highest percentage for display. My highest normally is cell standby or phone inactive.
So, does that mean that our phone part of the handset uses much more power than the phone part of other devices? Or does our display just use less? Or is the reporting simply different from other android models?
Since my battery goes down faster when display is on, I cannot really believe that display consumes only 3% of my power. Otherwise, when display is on, the processor also has to work so that might be the reason for consumption being higher with display activated....
Any thoughts on that?
Thanks!
Did you see my post? http://forum.xda-developers.com/showthread.php?t=1193402
It could be similar in some ways.
What do you see in Spare Parts? In the network usage ( Spare Parts -> Battery History -> "Network Usage"). Maybe your network is active when the display is on.

Yesterday I noticed that I could not turn on the phone. I had to hold the power button for several seconds to reboot the phone. Today I looked at the battery details and saw a gap. I did not turn off the phone and it did not reboot by itself (since I didn't have to unlock my SIM card). I just rebooted once because I changed the DPI from 320 to 240, but I don't assume that would cost so much battery. I'm on a stock ICS ROM (4.0.3 / rooted).
Any ideas what could cause this?
The explanation in ficticeous battery charge measurement on all current devices. The battery charge is a estimate, not something measured with 1% precission. After the reboot the software interprets the current battery voltage differently.
You can see that effect on phones, laptops and anything powered by batteries.
The same goes for another question from other user this morning, battery % drops faster once you go below 50%. Yes, this is normal in many devices, and has the same explanation, the phone has no way to measure the battery power left, it just guesses from the battery voltage, and the curve changes with the power ussage, temperature, etc....
The gap appears when u restart ur phone
Checked Android market. There appears to be no app to monitor
and display the current consumption.
Most apps show power remaining in the battery in percentage format.
Not much use. Its a crude approximation. Because idle current
is a good indicator of the overall device status.
Showing the current consumption is more useful because
it shows up abnormalities if any. Some apps just kick in the
CPU into extra drive and the current consumption goes up very high
( 600 mA or more ) and the phone starts to heat up fast.
Besides heavy current drain is also harmful for the battery as well as the phone
components.
The ideal Battery current drain app should show the current consumption
( idle mode ) in mA, in real time or every 15 seconds or so, with the display
changing colors to highlight high current drain.
Normally as the battery voltage goes lower ( depending on usage time ), the
idle current drain would be higher because the internal inverter driver will draw more
current to maintain constant voltage supply to the CPU and display.
This is normal.
Whereas when the battery is fully charged , the actual idle current would be
the true indicator of the idle current of the device. Hence an elapsed time
display ( in hours, minutes ) after the battery is fully charged would be
an additional help.

Hello Gentlemen!
Im new to here and welcome all..
After one week communion with my new 4xHD I have a real problem with the battery. First days it works perfect - when I didnt touch my phone, it consumes a minimum (through the night ~5-10%)... Of course when I was doing something intensive battery is sucked totally out. Then I've decided to optimize it a little, I install quandgearbox 4xhd (according to the recommendations here), then battery monitor widget... and in the first hours all was nice - flat consumption battery chart (night consumption fell to ~3%)...
and suddenly, I have no fcuking idea what I did, but I did it indeed.... battery is killed in ~6-7 hours totally... Ive checked all background processes, any suspicious apps, clicked on optimize in android assistant, restarted phone.. and I dont know what should/can I do more..
advice me something please...
Warm regards,
Daniel
ok guys, I've found the culprit... quadGearBox has some bug - even if you see "eco mode" checked - it does not ensure you that is in fact.
So the last day my 4xhd remained in quad-core mode all the time. I can verify it by antutu for example - in true "eco mode" there is about ~9500 points, in full quad-core mode I reach ~14200 score.
I've reinstalled it, restarted and all looks nice now.
Regards,
Daniel
Hey,
I've got a few questions I'd like to ask the Xerpia commuity. I'd like to say that I love this phone since upgrading from my SG2. I have the Xperia Z from T-Mobile and look forward to creating themes for it.
1. I see that some people have mentioned setting the bightness slider to a certain level and using the auto brightness function when they work to save battery life. How does this help in saving battery life? Is it setting a level for the screen not go below and then letting the sensor adjust more brightness if needed? I usually set my devices to 1/4 of the way with sensor off thinking the sensor measuring light would be an extra drain on the battery.
2. I'm new to this device and the only hesitaton to get it because of the built in battery. I've owned plenty of smart phones to know the battery life is truely dependant on how you use it; use it more and battery drains faster etc. There was no expectation that this one would be any different. Has anyone had good results using an external battery pack to charge the phone on the go? If so which brand would you recommend? These things have dropped in price over the last year and I'm considering getting one to take on trips or events where having access to a plug wouldn't be a real option. Many of them claim to charge phones 2 or 3 times on each charge (depending on size of the batteries at play of course).
Thanks

Good questions.
Personally I use the brightness slider at about a 3rd with the auto on, I also have a toggle in the drop down notification that dims the screen on touch, you can find that in settings - display - quick settings. I find my battery life to be perfectly acceptable, it lasts all day as long as I don't do any serious gaming or massive uploads/downloads.
As for external batteries I personally have one of these...
http://www.amazon.co.uk/KingMansion...tery-Xperia/dp/B00EOKQ5E2/ref=pd_sim_sbs_ce_2
It's 4200mAh so a decent amount more than the Xperia Z itself, 2330mAh if I'm right. It isn't too expensive at £17 (don't know what that is in foreign money). It fits well and charges the battery at about the same rate as the mains charger except it's through the pins.
The Z has a great battery, it could be better but then what phone has a perfect battery. Just don't go crazy on the heavy usage, you'll destroy the battery in minutes, 40 minutes on GTA:Vice City and my battery is gone.
For everyone having high battery drain on cell standby on 5,1, I think the issue isn't as bad as the Android battery stats show in settings. I have installed Gsam Battery Monitor and the stats that the app show, are way different then the stats that the battery settings show. The Gsam Battery stats look much more realistic.
I have the stats from a day and a half, but I didn't turn on cell data, unless I needed it, which gets rid of the cell standby bug on lollipop, so you don't see the high cell stanby issue. Today I will keep data and WiFi on and post tomorrow, just to show the high cell data battery usage on Android settings, compared to GSM Battery.
Notice the screen use is 20% different, the WiFi is 4% different, which is almost a third, even with data off to stop high cell stanby battery use, my radio uses a total of 9%, but GSM battery app, has a total of 3%, which is 2/3rd less. The only thing, that looks correct is app use in settings battery.
It will be interesting to see the difference on cell standby and phone idle, when I have WiFi and data on the whole time, which makes the cell stanby use like 50% in the battery settings stats for me normally. I will post when my phone gets low

These effects are not bugs in general. LP just has bad description of what Cell Stand-by is exactly. Same goes to wifi and other stuff.
It's also very bad idea in general to claim bugs, when you have so little info to rely on, let alone how accurate the tools you use are.
Unless you got direct access to actual measurement of a given component, everything goes in the realm of hugely distorted approximation.
In other words, you're wasting your time.But hey, it's your time after all!
Um this is a well known bug not claimed by me lol
Play store services says 30% in the Android settings and 1.2% in GSM today. The cell stanby us at 20% in Android and 10% in GSm
Just wanted to share that the battery life is very good on the X9. I am getting about 5.5 hours of screen-on-time.
I unplug the phone at 6am and at 11pm there is still 15% left with at least 5 hours of SOT.
That's excellent, I'm only getting around 3 hrs SOT myself.
Yes, I confirmed it. My X9 is in good battery life, normally I only need charging it once per day, even if I used it to browse web, some gaming.
Same here. SOT is consistently 5hrs+. This includes some gaming , alot of web browsing and some music.
Screen at 40% , 4g off , battery saving location setting and haptic feedback/ touch sounds disabled.
Everything else default.
Even if fast charging is only ver. 1.0 battery life is good enough to not need faster.
Very happy with this phone all around.
Slightly disappointed with the battery life. The standby power usage is not great compared to my other modern android phones. It is lightly debloated with all the power saving feature on except power save mode. Using power save mode only brings it to about the same level of my other phones without it on... Then, there is my Z3c.
~5hour screen on time is not great as well. Comparing similar screen size phones, it is pretty bad as I get about 6 on my Note4 (which is faster and pushing a higher resolution), and Zuk Z1 (CM13 with undervolt), which easily get 9-10+.
Edit: Some overnight numbers.
My main phone is an S6 and before going to bed was @ 43%. Checked phone 11 hours later = 38%. This is with wifi on and syncing 3 google accounts, 1 IM, NO SOCIAL MEDIA.
X9 @ 52%, with Wifi, sync off (no IMs/SM installed), no BT, no location, 2 SIM active (both get 5 full bars @ connection) = 41% checked at the same time. Doze is on and confirmed working. I've used with only 1 SIM before and it really doesn't change the numbers that much. I wouldn't be so harsh on the phone if it had quickcharge 2.0. But it only charges slowly @ ~5V 0.96A. There is something funky with the charging numbers, since it bumps up to ~1.1 amp after ~80%. It also doesn't trickle charge after 90% and only drop to trickle charge after hitting 100%. I am not sure about the battery longevity on this thing.
I had bought my x9 2days back battery drains very quickly.....disappointed any solution plz

Same with all phones... check all which apps are the most hungry.
If you suspect its an hardware issue, factory reset then uninstall/disable as many apps as you can, charge up and let it run and see if it last normally.
Usually it should be some apps eating up the battery.
Dears All
There is an app (3C Battery Monitor Widget) in which you can inspect your battery to see if it works in normal condition or not. It shows you amount of real amperage drained from cellphone battery in different situation.
As I tested mine (htc one x9) it drains maximum current when capturing photo or recording video, location(gps) is on and map apps like google map is live, switching between different applications which result to rise frequency of cpu up to maximum (1.95 or 2.2 ghz in different model).
If you enable power saver mode in setting, maximum frequency of cpu wil be limited to about 1.32 ghz and conserves more battery and limits drained battery current below 900mA otherwise in aforementioned cases drained current will be raised above 1000mA and it is obvious that (3000mA/hrs) battery will be empty during 3hrs. Anyway normal application such as web surfing (specially with WiFi instead of mobile network), listen to music, talk with phone and brightness of display below 50% will result to more than 5hrs SON.
If you need more battery SON, one way is limit CPU/GPU frequency and some more sophisticated setting (you should first unlock boot loader, then root and also install kernel application or change stock kernel with custom kernel which can support change of CPU parameters the former is easier and the latter I couldn't find until now anything)
Finally I would be happy to announce you that I could reached 8 hrs son with this technique on my HTC ONE X9.
Battery life is quite good on my device too. Although I have disabled touchboost.
To disable touchboost open build.prop and change
ro.mtk_perfservice_support
From 1 to 0. Root is needed though.
Also limited max. Freq to 1.7GHz
1.9GHz is just an unnecessary heat generator and battery drainer.
