Hi all, based on my experience of flashing various different ROMs, most of the ROM shouldn't have the battery drain issue. However, I discovered some times after flashing a new ROM the device gets much warmer and the battery drains very quickly.
When this happens the best solution is to shutdown the device, pull the battery out for 5 minutes or so to let it cool down. Then put it back and turn on the device and the battery drain problem should be resolved.
I haven't been able to find the reason behind that but it does make a big difference. With one of the ROM I flashed, the battery went from 100% to flat in less than a day even when no WiFi and no bluetooth are turned on. Then I recharged the device, pulled the battery out to let it cool down and put it back. After that the battery went back to normal with only around 3% consumption overnight.
I guess this is because with a flash of a new ROM the learned parameters for the battery will be erased, too:

So the more charging/draining cycles you do this should improve again.

I've been searching but haven't found what I need.
Yesterday I was playing a game and my phone froze so I did a hard reboot. I was at 77% before the reboot. After the phone turned back on I was all the way down to 41%. During this time my phone was running very hot. In fact it ran hot all day at work and wouldn't charge. After the first battery pull, the battery dropped I did a third battery pull and things turned back to normal.
I'm running Blend 7.1 with the FD02 kernel and FD19 Modem. Going to update my kernel tomorrow. I just switched back from AOSP. This has happened to me in the past as well.
Our phone anticipates battery drain. I've had the reboot battery drop, but despite the lower percentage, the battery drains slowly and increases during sleep.
You're not actually losing battery capacity; the OS is anticipating quicker loss and reflects as much with a lower percentage

Awesome. Just wanted to make sure it wasn't something that I had done wrong.
Hello,
I've read the threads about battery in the desire, BATT FIX with new kernels etc but can't really find a definite answer for my problem.
I bought my phone 18 months old and from the beginning it has shut down at about 20%. Tried the battery thing with charging, on/off, charing again etc, wiping battery stats etc but it doesn't seem to matter. So, I thought I'd just buy a new battery and be done with it.
The new battery arrived yesterday (actually, it's a used battery from customer returns but seller tells me it's been tested to be in mint condition). So this battery shows 3% when I first start up with it, "good, this seems to work" I think. But when at 75% the charger indicator (LED light) all of a sudden turns green and battery % jumps straight to 100%. I do the battery calibration trick with on/off charge and wipe battery stats. Stuck at 100% for some time as reported by others trying this "trick", have been using it all day and it shuts down at 25% even worse than the other battery...
The best voltages I've seen on this supposedly new battery is 4,144 and somewhere above 3.5 (nowhere near 3.2 and 4.2). What strikes me as odd is that I get very close to the same values with my old battery so I'm starting to think that maybee both battery are good but the phone reports way wrong values...is this possible?
Battery life with phone and data connection on, 1 gmail account but disabled backup feature (no GPS, BT etc) gives me -5% after 10 hours standby and I can use the phone for browising, light gaming for about 3 hours and 40 minutes before it dies (more or less constant usage at very low autobrightness levels and Turbo 3G enabled).
If someone has some insight into this it would be really helpful before I contact the eBay seller for this particular battery.
Regards, Olle
Same thing
My phone shuts down at 35% now... Is that a problem with the chipset or what? Only with Alex-V's calibrated kernels my phone shuts down at 0%, and sometimes it decalibrates too, but after calibration is Okay. I wonder if i need a new battery or my chipset has issues.
Hi guys. Im new here. I just wanna share about my Z1 compact latest battery problem kinda frustrated me lately.
I bought the phone 2-3 months ago, already with Android Lollipop 5.0.2. Since the purchase, I didnt really face a problem with the battery life as it lasted about 12 hours per charge due to my heavy usage of the phone.
But a few days lately, my phone being worrying me as the battery doesnt being as normal as always. For example, it can drain the battery drastically from 88% to 67% in a few seconds when the screen is off (in standby mode). Sometimes, in the middle of the usagefrom 39%, the phone suddenly shows the battery low warning with a 1% battery remaining, and without having enough time to reach the charger, it shuts down by itself.
In rare cases, I caught my phone drained the battery drastically when the screen is still on from 15% to 1% less in a minute.
The phone wasnt rooted and I didnt anything else besides my daily normal usage. The latest apps I downloaded before the problem occurred is Waze.
I tried everything to save the battery like using the Stamina Mode, force stops some apps, slides away all of the running apps in the background but failed. I even factory reset my phone and installed all the apps the way it used to be but still didnt solved the problem.
I still have about 8 monts of Sony warranty but I need you guys help first because I need to use my phone for work right now. Please help and reply.
Thank you. *Sorry if my English isnt that good*
When the battery jumps from 39% to 1%... Does it stay a long time at 39%? Or from 39 to 1 in few minutes?
Just curious...
Sounds like a warranty issue to me. You could try to find out what is causing heavy drain like with BetterBatteryStats. But no app ever should cause such drains.
Sound more like your battery is not okay.

The exactly same problem with me .I have 100% battery and indicator stays 100% for a half hour than drastically drains to 1% and shuts down.
Change your battery! I had the same Problem. I changed my battery with anotherone original from Sony, but a few weeks later the same Problem: quickly battery drain.
So I ordered me a battery from e-bay but NOT one from Sony! Now a few weeks later still NO Problems. Everything runs Ok now. NO battery drain at all.
Ok guys,yeah it's 5 years old already.Few days ago I noticed then when I charge it to 95-100% and leave the tablet turned off,when I turn it on battery looses like 10 % over a day and so on,so battery is draining when the tablet is turned off.
What can I do,I mean I can take it to a friend of mine who is pc technician but what can he do?
Possible hardware failure or battery issue?
If the battery has lost much capacity it will still charge up to 100%, but discharge much quicker.
If screen-on time is still okay, some peripheral component may not switch off when powering down. Some custom rom had messed up an old phone of mine and even after flashing stock rom the battery drained by 50%/day after switching the phone off. I even ordered a new battery to no avail.
If the Note hangs up or freezes during power off, you'd need a hard reset to power it on again and the battery would be completely drained in less than a day.
Self-discharge on my Note is extremely low, about the same as if i would store the battery separately or with a hardware power switch.
Screen on time is terrible like 2h or so...which means battery is bad,right?
Bad battery or bad configuration. The latter if the Note is drawing more than 1000mA when idle with screen on.
My battery still lasts about 7 hours (screen-on) and is the original from 2k13.
Battery lasts for like 6 h,and it's draning power when is switched off...I'm not sure how much but maybe like 5 % per day...
And I also noticed time and date is fuc..d up...
Can this be resolved?
So now even new battery can not last more then 4 hours,today tablet turned off at 30 % battery,I got flashing blinks and it turned off.
When I charge tablet it doesn't charge like in the start for 8-9 hours,usually 4,5 at max and when I check on status I see 70 % and then in a second 100 %.So smth is pretty messed up..
Seems to me it's for garbage only...
The Android Coulometer could be ****ed up. Although that should be more of a database than a driver, you could repair it by flashing the Coulometer driver via ADB. Only for stock rom. And there was only a guide for my old Huawei Mediapad on how to perform this.
A complete factory recovery in Download Mode will have the same effect. Or it may just slowly get better with time again, as it did with said Mediapad.
I once experienced real drain in soft-off state of an old phone, about 50%/day. A new battery didn't help. And the phone did really switch off, otherwise you'd have had to press power for 10s instead of one, for a cold boot. And with even higher drain.
A custom rom may have flashed a wrong firmware into a peripheral chip's flash. In case of said phone i suspected the wifi/BT combo chip, which retained a custom rom's bug even after flashing stock rom in D/L mode.
I was told that this is hardware issue.
What is factory recovery and what will it do,and how do I do it?
2.I can't update to android 5.0 at all.
When I click update manually get msg: you have recent update smth like that...
Hi! My old battery was inefficient (45% health at AccuBattery) and it swelled so I decided to replace that one. Everything goes easy because it wasn't my first battery replacement in this phone but just after replacement I noticed that the new battery is draining fast also. I was operating on MIUI 12 by Xiaomi.eu, so I decided to rollback to Stock ROM with MIUI 11. I flashed it with MiFlasher (With full wipe). But still new battery was draining fast (51% health) in AccuBattery. Then I want to make sure if this new battery is actually new, so I bought another battery, but this time from other company with good rating and replace it. And this do nothing because the newest battery phone is using only with around 50%. I tried to recalibrate battery once, I drain phone to 0%. And then I want to charge it to 100% without turning it on, but it turns on automatically and it gives no effect.
What should I do now?
Only one right way is to measure battery capacity with special charger. Something like this.
Drain battery to 0%, turn phone off, connect through device, and charge to 100%.
