Big battery drain after last security update - Xiaomi Mi A1 Questions & Answers

After last security update, April one probably, I have to charge my phone twice a day instead of once, battery drain is literally double. Nothing suspicious when I check battery app drain too, everything shows like before there.
Anyone else experiencing this? Any tips?
Cheers!

I have the same thing for a couple of weeks now. I installed simple sysmon and it shows all cpu threads working at a 2.02ghz which is their's maximum, so I guess this is why battery dies so fast now. But I can't pinpoint why, seems like planned degradation to me, which is a shame.
Restart helps for a 10-20 hours, but I'm getting tired of restarting it all the time)

i have the same problem

Interesting battery performance...

OK, I've had my HD2 since November, and I've never understood people who complained about poor battery life. I've consistently been able to go up to 2 days before charging. On the odd occasion, I've left TomTom running and it's drained the battery right down, but overall I've been pretty content with the battery performance.
Until about a week ago. I thought I'd maybe forgot to stick it on charge overnight the odd time, but now realise the battery has started to drain much more rapidly.
I did not change ROM, or install any additional software. I made sure nothing was running that shouldn't be in Task Manager. All of a sudden, I'm getting quite random battery drain - up to 20% drop in an hour. I put up with it for a week, thinking it just needed a hard-reset, so last night I decided to flash a new ROM. I updated to the latest radio ROM, and flashed bobsbbq's latest ROM thinking that would sort it, but after I took it off charge this morning it was down by 15% within an hour.
The drain has levelled off throughout the day, but it's still much higher than I'm used to. I don't use wireless, and I only have bluetooth turned on if I'm on AC power, so I've just got GSM/3G in normal use (and get good reception at home and work).
The fact that the battery drain changed so much in such a short period of time, with no obvious change in usage or software leads me to believe the battery itself is beginning to fail. I usually expect a good couple of years from a mobile battery before I see noticable drops in charge, but that's 6 months.
Is it possible the HD2 batteries are not very well made, resulting in some people having great battery life, and others complaining that it's crap?

I had read that some of the HD2 batterys were a bit dodgy as they were siphoning off the batterys from different manufacturers and as a result some are remarkably better than others.

I am precisely in the same boat. I am using my battery now for around 6 months. Since last week the battery seems to drain much faster than before. I am still analyzing what could be the reason, but I think it's the battery itself that is getting weak - far too early.

You said it yourself, the batterys performance gets worse for every day and should be replaced with a new one every 6 month, atleast.
Some feedbacks in other threads pointed out a possible and unforeseeable cause, the microsd card.
Try removing it and check battery drain, if that's the culprit try formatting it before throwing it away.
Also, as I stated in at least 3 other threads p) it's always a good idea to check battery drain with battclock, it should be 4mA during standby, any big variations from that mean something's draining while phone should be sleeping instead.

Yeah mate, that's laughable. I've never had a mobile phone battery go within 6 months. Are you trying to jump start your car with your batteries or something?

Horrible Battery Life after Installing Android! :(

After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

You can look at this thread
http://forum.xda-developers.com/showthread.php?t=770903
It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .

98% deep sleep but 48% battery drain? What gives!

I charged my phone for a little bit last night because it was a little low (48%). I took it off at about 77%. I don't understand what happened. Why did it just drop like a rock? Phone is AT&T LG g2, stock 4.2.2 rooted.
Jesus that can't be good.
I have no clue about this one; it's just too weird.
I'd probably let it fully deplete and then completely charge it and see if it ever does it again.

That's what I'm going to do. Unfortunately this is not the first time it has happened. This happened about 2 weeks ago, but then my GSAM showed a HUGE signal decrease at the same time my battery drained, so I figured it was just that.
This time I just do not understand. I've had this phone since August or September and it's been great until this randomly started happening in the past couple weeks.

Well it says 66% of that was phone radio signal. So that is the problem 90%. I had similat problem only it was while charging, so my phone wasnt charging almost at all, when i restarted it was charging fine (from 20% to 100% in 90 min) . What happened when u picked it up, was it still doing that? Or maybe its a some kind of cpu loop if that is even possible. Some people was complaining about nexus 5 rapidly discharging with combo of some lite apps (news readers).

Yes even after picking it up, the drain continued. I've let it die and am charging the phone while it's off but I don't know if the problem will be fixed.
The youtube app was causing a major battery drain for me a few days ago,now I close it after using it just in case . I'm in the habit of checking the phone's temperature at all times :/
it has a great battery life, especially sceen on time, but the standby isn't top notch at all, I think it's poor software optimization on LG's end, I hope 4.4.2 fixes it.
charge till full. then reboot and check battery percentage.
send from the jungle

I love Android :3

Battery drain with or without wake lock, doesn't matter. :good:
It has nothing to do with Android, on average i'm getting 3days with 6-7 hours screen on time on every charge.
So either you have app that drains battery or your battery is malfunctioning. (or both)

Well, I don't think it's an app that is draining battery as, there are no wake locks and I don't use apps that run in background except Google apps. I don't think it's a hardware error either because this doesn't always happen. It started to happen a few days after I got the Nexus 7 half a year ago, then stopped and started randomly. It hasn't happened for at least 2 or 3 month until one week ago.
I also own an Android phone(a Samsung Galaxy S2, I know it's old) and wake locks happen so frequently, sometimes I wake up (after only 6-8 hours) to my phone having discharged completely. Betterbatterystats shows wake locks on my phone most of the time but they are so generic and not attributed to an app(i.e show up in the partial wake locks tab) that I can't troubleshoot. And why do I always have to troubleshoot? Why would I have to turn off all services to ensure I get through the day with 1 charge. I don't even use my phone a lot.

Let us see the BBS logs for your phone.
About the tablet, flo has never had good idle drain, but this is likely a problem with your wifi. Before you go to bed, turn off wifi and reboot. See if you can still reproduce the 3.0%/hr drain.
If that doesn't make a difference, recommend trying stock ROM and especially kernel.

Is he using a NON standard rom and the guy is *****ing about battery problems LOL
One word of advice, regardless. Do not let your battery drain completely. Ever.
Lost my Nexus 7 like that, the battery life is great so I was lazy to enough to charge it before going to sleep (it was on a very low level then). Got a thin brick in the morning
Charge it before hitting 20% battery to be safe. That is what I do. It expands battery life longer for me

It does work besides there is no damage if you let it die just a few times but if you let the battery discharged till it dies frequently then you are damaging the battery. This is more common on Li-on battery as they drain more quickly overtime due to frequent loss of power.

Hmm. Good to know, thanks. I rarely let stuff die completely, but now I'll actively avoid it.

Battery issues, confused.

6P has been shutting down early for a while now, usually like 10% or less which never really bothered me. Battery life seemed decent, but I never really tracked it.
Last week it started going off at 15-30% at times. But it can be random. Might go below 10% one time, next shuts off at 30%. This was on a prior version of Pure Nexus. So I tried updating to the latest build. First charge it shut down at 40%. Same crap tho, random shut off times. Today it shut down at 48%. By shut down, I mean it just suddenly gives the low battery warning, reports 0% and turns off. Many times I can restart the phone, and it will say like 1-3%, and let me use it for a while before turning off again. This most recent one at the 48% shutdown, I restarted it, showed 1%, used it for a while before it turned off again. Restarted, now shows 18%.
Wtf? Is this just a charge level reporting issue? Tried battery repair/calibration apps/techniques with no success. Nothing looks bad with regards to apps/services draining the battery. I tried accubattery and says I'm at 70% health. Don't even get 2 hours of SOT. Have a replacement battery in the mail. Think this will solve the issues?
It's known issue with some factory battery's for some reason the phone is thinking the battery is low and shutting down even though it's reporting let's say 50%. I didn't have this issue until I bought a cheap replacement would shut down at random percentages especially when opening something power hungry like camera. The only thing you can do is get a replacement and change or send it in to get changed. If you replace it yourself I suggest testing the battery before you put the phone back together. I think the 6p is a great phone and worth it to replace the battery. That just my opinion best of luck. ?

@ 70% your battery has been toast for quite a while. This degradation doesn't happen overnight. If you did your research and purchased one of the "good" replacement batteries from a known good vendor then, yes it will likely completely solve your problem. If you just bought a random battery from Ebay or BFE, then you may have another dud on your hands. Suggest testing the new battery with Accubattery before sealing it back up. Best of luck.

Interesting. Did notice a couple of the times it shut down, and it was this last time at 48% as well, was when opening a power hungry game. And yes I agree the 6p is still awesome today, by far the longest I've had a phone. Considered getting the Pixel 2 XL, but it's a waste of money to me if I can get the 6P working well again.

Hmm, yeah I grabbed one off ebay. Had over 500 sold though, so hopefully not too terrible, but I will test.
I think it has really degraded in the last ~6 months. Possibly from numerous partial charges? Got a new job in April, and I'm often traveling to different sites only 10-15 minutes apart. During this time plug it into my car for Android Auto.
Thanks for the help guys!
In the same boat (But I have a solution for me)
2 weeks ago I upgraded from a beaten GS6 Edge and I am quite fond of my new phone. However I started experiencing this issue, ignored it for the first week since my S6 at 100% battery would die in an hour or two, if I'm lucky. Then the battery problem became an interest to me. I had read a lot of threads on the issue, some saying its a hardware problem, and some saying just a software bug that hasn't (or can't) be fixed. SOOOO at this point I said screw it and just accepted my phone battery as it is. Installed Dirty Unicorns Rom, messed with settings, and boom a breakthrough (I think). DU has a feature called smart pixels in which to save battery life turns off a percentage of the pixels. Wasn't to fond of this at first, but in order to make my 60 - 70 percent battery last i set it to the lowest setting. Every since then I have had maybe one random shutdown, it's only been a week and a lot could change but for me its working pretty well.
Sidenote: I found that not using camera apps, nor Google assistant had also prevented random shutdowns (this helped me with smart pixels enabled and disabled, if you wanna give it ago on stock)
Hello guys. I am experiencing random shutting downs on my phone too. I bought it in January 2017.
What I have observed and today was confirmed is that I have these unexpected shutting down when I charge the phone with fast charge. Today my phone was at 60% and shut down. When I plugged my phone on the charger, the phone was again at 60%!!! How was it possible? I think the problem might be the battery or the internal controller of the charging system...
