Battery issues (GingerBread)

It seems that 21A has the same battery drain problems as the 10B. The phone works ok, but sometimes has spikes of consumption of 400 or even 600mA, and sustained consumption rates of 150mA.
From the comments in a Spanish forum, it seems a common problem, but it's weird I haven't heard anything about it here.
And no, wiping battery stats didn't solve anything.
Here's a nice screenshot of a complete charge on a lazy Saturday. No calls, no gaming, almost no anything.

I have the same problem, from 100% to 33% for one night.

My problem is different. My battery lasts more than before but i cn't get the stats correct. After rebooting the device the battery shows sometimes few hours since last charge or sometimes few secs after booting and keeps showing few secs even mins after teh reboot. I've wiped the bat stats in recovery as well but nothing.

I found that the phone loses signal with leaked baseband causing a drain. With official i have no drains. Are you sure there isn't a app causing this?

[Q] Battery is dying multiple times a day, need help!

Hello everybody!
My HTC Sensation is acting kind of weird the last few weeks.
It all began when i flashed CM 9 on it. It worked great, but pressing both the volume button would cause it to crash, so i flashed CM10 (kang) to it.
Now what happened at CM9 already was that it would just turn itself off at some points. During browsing, or taking a picture, Or just sitting in my pocket.
I had a almost full battery at that time(about 70%+) and it just went dead, reboot would give me 1% left. In CM10 the same problem happens. This time i took screenshots of the battery management screen, i included them in the attachments.
I wiped battery stats even tough it is a myth but could always try it. Did not fixed this.
Now the funny thing is when i reboot the device and it says it has only 25% left of charge. It reboots and BAM i have 75%, Reboot it once more and i lost 10%, rebooted again and it kind of stabilized. Now i have it on the charger and i am watching it, the LED on top stays on orange for about 2 seconds, then turns to screen for 1 second and then it turns of. then it just cycles trough the same again.
I hope i am making myself a bit clear about this and i will answer all questions i might have left out that are important.
Please help me because i cannot trust this phone anymore, it dies without warning and i have to boot it to find myself stranded with 1% left (which ironically can last for hours if the phone doesn't die).
PS. I included 3 screenshots. The first 2 are from when it died 2 times, as you can see the dips.
The last one is when i rebooted it and it gained allot of percentage.
Thanks in advanced

Have you checked to see it if you have any wake locks? You can check with better battery stats apk. Also might be time for a new battery. You can get a good extended battery like anker for under 20 dollars,. My stock battery life was so bad, changed it to extended battery now it's really made a difference!

Hi,
I recommend you to see if you have any wakeclocks (Check via BetterBatteryStats)
You might have a bad flash. Check MD5 of ROM/Kernel
Check your running applications.
Let your newly installed ROM settle down for a few battery cycles.
But in your case, maybe a new battery?

I moved before few days from stock ROM to Bruces CM10 from 14.11. and have battery problems too. It drains to fast ROM is pretty stable, but with this battery life, I can hardly use it... Now I am on battery only for 10h 26min, display was ON for only 1h 55min and I am on 17% with battery... Something is bad

I have same probleme. I move from stock Rom to 11.11Bruce CM10 then upgraded to 14.11 but my battery life now very bad. I could reach up to 30h battery without charging with stock. In addition to that, I realized that the battery level could be significantly different from one boot to another : Phone show 41%, I reboot then it show 57%...
Need help but can't report on bruce thread.

It´s the same for me too... Battery skips on different values after reboot... For example when I am charging and battery is on about 90%, I do reboot and after that phone is on 100% battery... Weird...

Battery issue after 4.1.2 update

Recently I've updated my Note through OTA to 4.1.2.
I've spot that after update the Note is just draining the battery.
I could read about 10 hours on it before, and now it is only about 6 !!!!!
I even do not mention gaming, which is draining the battery in 2.5-3h from 100% to about 5%. I could play approx. 5-6 hours before.
It's ridicules.
Did any of you spot the same thing?
I haven't installed any additional apps after update that may "help" to discharge the battery.
The values above are based on Screen usage time in Battery menu.
Any suggestions?

After the update, I'm facing recharging issues. The tab is taking twice the time of what it used too to recharge to 100%.

i haven't spot any issues with charging.
.

Same here.Used to get 10 hours of screen on time,now i am lucky if i get 8 hours!

Same here...
Some tips :
Kill all apps, switch to offline/airplane, and power saving mode when charging..
Still not working?
Try reboot your device once or twice if necessary..
And your device will charge normally
Work on my gnote...
I hope it will work for you too
Correct me if i'm wrong

Im using juice defender with good results, I lost a pretty noticeable amount of battery time after 4.1.2, too.

Maybe a problem with the battery stats?
Try to drain the battery empty and full charge afterwards.

It will damage the lithium battery when you drain it till empty

I think it is Wi-Fi that drains the battery !!!!
Usually I was leaving the tablet with wi-fi on all the time. After 4.1.2 update it takes approx 2% of battery per hour !!!!!!!!!! when you do not use the tablet but wi-fi is on, so after night in the drawer you had approx 10-15% drained.
When I turned the wi-fi off and left it overnight i haven't loose even a 1% during the night !!!!!
I have to try to work on it as usual but with wi-fi turned off, it will be difficult though as usually i play on-line or browsing the net
I think they f#^%*d something in 4.1.2 update with wi-fi energy consumption. hope they will repair it in next update.

I mean, just let the device turn off by itself, and after that, charge 100%.

Yeah, I had this problem after I updated too. It was also laggy. I did a factory erase and now it works better. I think it is still draining more than before, but not as bad as after I updated. I think a good rule of thumb is to wipe everything after an update and start all over. You could also try wiping and flashing the rom for a fresh install.

I suggest you to change your rom to germany stock 4.1.2...
It will solve your charging problem

Battery drain and calibration issues.

So I've had my falcon for about 7 months now and updated to lollipop. I'm in a custom rom now. But I had this issue that battery percentages drop whenever the device is inactive, but not the 1 or 2 % drops, maybe 10 or more. I use the phone to text a lot, and when I reach around 19% of charge left the phone shuts down.
I read that it might be a calibration issue so I tried the battery calibration app bit didn't seem to work.
Any way to solve this or any ideas?
I will attach my last battery log.

Mate P7 Bad battery drain in standby

Hi XDA,
I'm having some problem with my Huawei Mate P7,
Recently when the phone is in standby, it can drain the whole battery from 100% in a night of standby(while sleeping).
I've reset to factory hoping that would fix this, same problem. I updated to latest Lolipop thinking that would help, same problem...
When the phone is in Smart Power mode and I'm using it while on, the battery hardly drains. It's only in standby it seems to happen. Even not installing any apps except FB it dies.
It seems to be in the stats, 80% power usage is wifi/3g modules.
Any idea what could be going on here? Am I forgetting a setting? Is the battery a problem?
Thanks

Are WiFi settings are those?

Yip settings the same as the screenshot Except mine is "Keep Wi-Fi on during sleep - Only when plugged in"
So I charged it to 100% yesterday and left it switched off, plugged it back in and it had lost 40%, sitting at 60% remaining...with it switched off from 100% battery.
Starting to think the battery is dying Attached pics of usage..brand new software, reset, no apps installed, running on Smart Optimization

same battery drain. Updated to 6.0 and the problem is gone.
4.4 was fine. But all 5.1 had the same battery drain issue

Thanks for all the assistance all, I think the battery is just going bad, it takes forever to charge, leave it charging all night sometimes and its still not full tried multiple chargers too
Can't get more than 6 hours out of it it seems tried all suggestions including upgrading to 6.0(made a difference with speed much quicker now though)
Anyone got any other suggestions??

How good is your mobile signal?
If it's trying to use 4G and searching for better signal it could chew the battery. It's much easier on battery running on 3G.
