Hi,
On my One-X battery meter is completely inaccurate. Sometimes it sits for hours on one value (e.g. 90%) and then suddenly drops (with no CPU/data activity whatsoever) to for example 80%. This results with very jerky battery use graph (attached mine). I am on 1.29.401.7 and done multiple full discharge/charge cycles, but it does not make any difference.
I have never seen such bad battery meter behavior on any other Andoid phone. Have you got similar problem?
I have the exact same problem actually.
Same here. It's as if it doesn't update the battery meter when it's in sleep (fifth core running). I suspect it's because of the T3 architecture and power management. As soon as you wake it, after maybe a minute, it updates the battery status...
Mines does it. Can sit on a %age for an age then with little use it will plummet.
@Op,
No I didn't notice such a problem on a unrooted One X and with no modifications running the latest OTA update 1.29.401.11.
Did you play with battery apps or did you modify something yourself which could cause this issue? Did you investigate what could cause it?
How long do you have your device, did you install apps? Can you provide more info about it maybe? Do you softreset your device?
Did the problem exist when you bought the device?
Thanks.
So it must be general problem then. It happens to me not only in sleep mode, but when browsing the web, etc.
I think these sudden percentage jumps and meter inaccuracy also contribute to all these battery life complains from various people. I was personally shocked when after a few minutes of web browsing battery dropped instantly from 30 to 20%. It looks like crappy battery, but in fact seems to be just dodgy meter...

I have got the phone for almost a week now and I am pretty sure this problem has been there from the very begining. I initially though this is because a couple of full charge / discharge cycles are required to calibrate the meter, but it did not make any difference. My phone is not unlocked, no mods or battery apps. I did not try soft reset though.
It looks to me that meter is somehow not updating during the sleep. When device wakes from sleep, after a couple of minutes value drops significantly. This problem is probably a reason for various false claims that One X does not consume a single percent of battery during the overnight sleep.
Yeah, i have the same thing. Sometimes my battery drops about 2 or 3 percent at once, sometimes 10 percent...pretty annoying.
Thanks for your reply.
I'm new to Android but I do have some Windows Mobile experience.
It's weird to me seeing people having such problems because I realy don't experience it.
My battery meter is constant, also after a night sleep.
Maybe it's because I use my device different as others I don't know, it's strange to see all these reports in XDA forum as the One X to my opinion is a very cool device.
Maybe you could try some battery percentage apps and see if it realy is that insufficient?

I used your excellent ROMs on my HD2 in dark WM6.5 ages . I am glad to see you here with One X!
I installed Battery Meter Widget and (if the readings are correct), my One X consumes about 10-15mA during the sleep with Wifi and 3G on. I will keep an eye on the percentage.
Don't get me wrong - besides of erratic GPS and dodgy battery/power management problems, I really love this device.
I really wished that international One X version was based on S4 SoC (superb GPS with GLONASS and great power management as S4 is a 28nm chip). It is such a shame that dodgy Tegra 3 ruins this excellent device...
Hello, maybe this behaviour is only due to the voltage sampling/display ...
Someone here says the native battery app was only at 5% precision at display
and it looks like it updates in long time samples too ( 5 minutes ? ) ...
Knowing that Li-Ion goes from 3600 mV ( 0% ) to 4200 mV ( 100% ),
it means 600 mV of voltage variation from empty to full, with 1 mV precision.
So 1 millivolt is 0.2% of battery charge.
The display should be really more precise if all voltage precision was used.

looking at that screenshot you have posted the sudden drops appear to be perfectly aligned to the 'screen on' or 'awake' periods so the most likely (and obvious) cause is that using the phone causes most battery use. I have seen this with many phones, I think its normal. Being in standby doesnt use much power at all but lighting the massive 4.7" screen and running a quad core processor does, so when you use the phone it uses loads more juice... thats my analysis anyway

No, this is different. Drop in fact seem to be related to wake up from deep sleep, but the point is that this drop is massive and instant i.e. battery instantly drops from 30 to 20, bypassing all other percent states in between. Also, I am sure battery state does not update properly in deep sleep in many cases. At some point I left my phone for almost a day alone (wifi, 3g, Gmail and exchange sync, etc) and it did not lose a single percent, but as soon as started using it I observed instant 20% drop.

And I have even worse problem, can anyone help me?
Take a look at my thread (not highjacking yours, just want some help too), my current widget never reads a real value AFAIK.
It stay with -850 for more than an hour at times...
And my battery life is dismal...
So this means that seeing no battery discharge throughout the night in sleep mode isn't due to excellent power saving feature of the companion core but is in fact poor battery meter?
And yes, my One X shows fast and huge discharge (3-5% at once) when I use after being in long sleep mode

I think it too. Phone on sleep with data and sync on for 1 or 2 hours and % don't change. Use it for 2 min. and it suddently goes down by 5/10%
In my opinion the battery meter lacks of accuracy. This brings to inaccurate real time current calculations and wrong information about what's consuming power when we use it. That's bad!
I'm also seeing these big drops. For me it seems to happen between 100%-60% battery, battery level will drop anything from 5%-10% chunks at a time. After 60%, it does seem to be more stable and drop in 1-2% increments.
I've recalibrated the battery through CWM a couple of times but still get this issue.
It almost seems like there's a bug in the code that is causing the fuel gauge to not update.
I can tell you this, I modified other HTC phones battery driver. The nexus one driver for example updates volt, percent, temp, every 50 seconds while the screen is on. When off the sample poll changes to 10 minutes per update. This is real easy to see in the driver code, and you can filter dmesg log for "batt" and see the time stamps do in fact match this.
But the one x looks to be getting hung up on that part. Anyone know if kernel code has been released yet?

I know it ibeta before you all start on me, however 15 minutes of web browsing = 10% loss of battery. At that rate my phone will be dead an hour and half of web browsing
When the phone is just on stand by battery life is fine

look it is same like brand new commputer (whit very good graphic card, processor, memory, MB) - you need good and strong power supply without it is crap ...
if you need good long working phone buy something else like :hmm: i dont know what maybe NOKIA with small BW display

I noticed on the JPC the battery drains soooo fast!
did a full charge while the phone was off today and also deleted the battery stats.. lets see if it improves

For me it all comes down "display on" time.
if using 3G/edge i get 4,5h
if wifi then 5,5h (no difference if im using it during 1 day or 4 days)
JPC is same as JP3 or JMx
Screen brightness
Just thought I'd say, incase you didn't know, the web browser has it's own brightness setting. That could be killing the battery.
I, for one, already set the brightness to the first level for all aplications that have brightness setting, and still the display sucks the battey like crazy, at list with JPC. With other FW it drops even to 40%.

Battery drain was ridiculous with me. The first night I went to sleep I remember my phone was nearly fully charged, when I woke up at morning it had used around 50%... that is, 50% of the battery for around 6 or 7h just sitting in IDLE! When I actually USED the phone it could barely handle 10h with a full charge, and that's with very moderate usage. I had to leave the phone charing all the time to survive a day with it (charging in my car, charging every time I stopped near an AC outlet, etc). And yeah, the funny thing was noticing how exaggeratedly high the screen battery drain was, even though I wasn't using the screen all that much...
Some other symptoms of the high battery drain:
-Charging the phone took FOREVER with the phone being used, took a LOT of time with the phone sitting Idle, but if I turned the off the battery would actually charge very fast... that proved that the phone was draining so much energy even the AC charger (or USB outlet) couldn't effectively charge the battery while supplying power to the phone...
-The phone got HOT very easily...
How did I solve it?
Well, yesterday I decided I would reflash my device. I did a full reflash (as I always do) including a re-repartion. Now the funny thing that I noticed was that my phone actually wouldn't flash! It would always crash at the Galaxy S welcome screen... I have never flashed it using my notebook (since I'm traveling), but I used the exact same procedure I always use with my desktop back home, for some reason it wasn't working. Maybe some corrupt file? I re-downloaded ALL files (that is, Odin with the 803 pit file, and the JPC files)...
For my surprise, this time my phone hanged in a green screen, and it was really scary. I even thought perhaps the Nokia USB cable I was using was causing some kind of incompatibility problem, but that would make no sense at all... so I entered the recovery menu in my phone and reset EVERYTHING, and tried flashing it one LAST time (this time closing ALL background apps in my notebook, to avoid any problems)... and there it went, a perfect flash, as easy as they go with my desktop PC back home.
1st thing I did was a hardreset, and then I reflashed it again with Doc's RomMod V2 (was using V1 the day before), and new hardreset in the sequence. Then I changed as little as possible in the phone configurations, I just turned everything off (GPS, wifi, and even the data connection through the power button shortcut), and went to sleep...
For my surprise, the next day I checked the phone's battery use, it had drained only ~4-5% for more then 10hours, this means it would, at least in theory, be able to last for days and days in this setup...
So I installed my apps again (not that I have many), did lagfix, turned widgets and network connection back on... and it has been working like a breeze, although battery drain can still be considered high, it's nowhere close to being as bad as it was before I flashed it, now at least the battery will last a full day with a charge @ my standards of usage, that's good enough for me...
One thing I did change, I remember my screen setup was always at 10/30min for shutdown, I left it like that because I'm always using the phone in situations where the screen will constantly shut down at my face, and that annoyed me... well, this time I actally left the stock 30 seconds for screen shutdown, not sure if it has anything related, but one of the things I noticed before was that my IDLE battery-drain was as high as you'd expect from a phone that had it's screen on all the time... maybe some bug makes the phone drain screen power even with the screen turn off, let's say if you have the 30min turn-off config, your screen will continue to drain power for 30min (and there you have the reason for so much screen draw in the stats), even though the screen is turned off... despite my hardware knowledge telling me that a black screen should NOT be draining power from your phone battery, you never know how far a software bug can fck things up hardware-wise, so I wouldn't be surprise if that actually DID happen...
I could even try setting my screen back to 30min-turnoff just to check if the battery drain will go back to insane levels.. but the fact is that I'm scared of messing it up again, it's working fine the way it is, why mess it up? I figured out some things that get messed up with this phone appear to only get fixed with a new firmware flash, and I really don't feel like having to flash my phone every two days...
Either way, I hope others here can fix their battery drain... it's just my tip: try reflashing, leave everything as stock as you can (only thing I did was Doc's RomMod v2, and later Ryan ZA's lagfix, none of them seem to be related to JPC's battery drain), and see if it helps...
wth I can only get 3.5 hours max
Sent from my phone so excuse the spelling errors
After a week of using JPC I don't see any real difference in battery usage from the original stock rom and JP3, I charge the phone every second night ( battery is usually around 25% at this point).
My usage isn't that high, I have a couple of notifications running and a weather widget that updates hourly, its my alarm clock, my mp3 player to and from work (about 90 minutes a day), I make and receive 4-5 calls a day and send and receive a dozen texts a day, I check face book 3-4 times a day and on a daily basis someone gets a 10-15 minute demonstration of the beauty of this phone(note: don't let a taxi driver play with your phone whilst in heavy traffic, even if it gets a confession that it makes his iphone look like a piece of crap).
As far as screen time outs are concerned, I set mine at 1 minute but always turn the display off manually when I finish doing something with it including after I have started the music player (btw I use bluetooth headset to listen to music but not for phone conversations).
The highest display percentage I have seen is about 85% but the is usually tied in with using gps or browsing, on a day I don't use gps or browsing display is much lower, on a day that the display is pretty much off it drops to about 10-15% usage.
This phone is the first, of the several pda/smart phones I have owned over the years, that I haven't had to charge every day.
Id battery usage is not a problem for me on JPC, 8hrs idle ( sleeping ) and I still got 100% started to use the phone and it rapidly dropped.. now im playing a 2hr movie and see if i can get it to loop for 2-3 times before it shuts off.. if it reaches 6hrs then i would consider the battery usage the same.
Please turn off the GPS and a-GPS....
You will get a much better battery life.....
A friend and I both have a desire, updated to the latest version of Android and running 5.09 radio. Neither of us use it extensively and I can get easily through the day on a charge, mostly having upwards of 30% battery charge left when I go to bed, while his can barely do 8 hours before needing a recharge.
He's already taken it to the store to have it looked at once and it came back performing the same.
I've been looking at his currentwidget log and the consumption seems fine to me, however the battery drain is much larger than I'd expect in return.

Anyone have any idea what's going on? Please help!
Are you two using same ROMs..??
I'm rooted, he's not, but I'm using basically the same thing. My battery usage hasn't changed, while upgrading from 2.1 to 2.2, his hasn't either. But his has been crap from the beginning.
Swap phones for a few days. Perhaps he's in an area where by reception is poor compared to you. The phone would use more power trying to get a better signal?
Sent using XDA App
Does he play games all the time? Does he use GPS, Bluetooth, WLAN? And you?
how does it perform in airplane mode?
Install Android System Info and take a look at the task list, CPU load should hover around 10-20% after a few seconds. If it's higher find the task and report back.
He said if he just leaves it on the shelf with sync disabled, no calls and no notifications, it gets 12 hours tops. I get 48 like that.
Does he use Live Wallpaper? I found out that if I use a plain picture instead of live wallpaper, the power drain is much lower.
Has anyone even looked at the currentwidget log?

Yep, and you're losing battery very fast in what looks to be an idle phone. Every few minutes the power drain is shooting up for a period and then fluctuating to higher than it should be in idle (between 7-70mA drain in idle means the phone isn't idle). Many services and widgets that are known as power hungry seem to be running too. Due to the logging limitations, I can't see if they are the ones causing power fluctuations or otherwise.
I mean, have you done any one hour experimentation with cell on vs. cell off to see the battery loss differences?
What about cell off, display off for an hour vs. cell on, display on for an hour - what are the percentage drops in both cases for the device?

Calibrate the battery?
I've read in a bunch of other threads that people are getting awesome battery life out of their Z or G2. Mine is okay-ish. I had a hero before which seemed a bit better. there are a couple of odd things I thought I'd check tho...
First, the keyboard backlight turns on and off at seemingly random intervals while open. Anyone else got this?
Also I've seen screenshots of the battery use screen showing how much power is used by each system. The screen always is at least 75% on mine, even when its been sat in a pouch most of the time with just a couple of messages or a phone call- this seems quite different to other peoples experience.
Is there any reliable way of benchmarking the battery to check? If not, does anyone fancy helping me test?
im actually suffering from the same problem,
i thaught it was because the first week i was using it lots thats why the battery wasnt lasting long, but on monday morning with a full charge ,
only with a few calls , texts and checking train times on TFL , by the time i got to sleep that night the battery was on 30%
I was shocked , checked the battery useage meter , everything was below 5% except the screen which was was on a shocking 80%
I Then formatted the phone , restored to default , removed everything ,
set the brightness to lowest useable which was just above the 'o' on 'ok' in the brightness screen let it charge to 100% for use on tuesday.
Tuesday - Morn before i left for work it was on 100% , the only thing i had setup on it was email, brightness on low - but useable .
Screen must have been on onliy for 20 mins throughout the day
Got home , battery was on 45%
battery useage - again display was taking over 70% of it when it was hardly on .
I am RMA'ing this one tommorow
I think its an issue internally with something shorting on the display, battery shoudlnt be draining that much if its not on
Out of interest was yours a UK Desire Z ?
Yep. This sounds exactly like my situation in every detail. I couldn't believe reports from other people saying their batteries were at 92% after 12 hours- even without using mine at all this wouldn't happen.
Mine is a UK desire z, from play.com. I think its over 14 days so RMA might be tricky, although I know I have lots of rights thanks to distance selling regulations. Hope I can exchange without too much fuss.
Ooh, just thought of something. When I set the brightness really low on mine (below 20% or so) the screen flickers slightly. It's most visible on a totally white page. Does yours do the same? Faulty backlight maybe?

Just tested mine, definitely no flicker.
Now my experience with the battery....
I play about half hour - an hour of games every day, plus about up to an hour wifi, using the xda app throughout the day using data, 10 - 15 txts and a few 1 - 2 min calls... Not too heavy usage.
I'm getting 30-36 hours, I'm happy....
BUT..... I have not plugged in through mains once yet. I read that charging through USB gives better performance... so far that is looking true.
I got the same kind of time out of my Hero using mains but that was with zero game time.
yes! pizza65 , i noticed the flickering too! , i thaught it was just my eye being twitchy ! Noticeable on internet browsing on low brightness! .
Mine was from handtec .. (amazon delayed too much) so changed last min,
it comes with a 2 year manufacturer waranty i think so even if you take it up with HTC direct they should be able to help if play dont.
I tried a diff radio and rom , but it made no difference.
Maybe the UK batch is still faulty , wasnt that the reason why it failed google testing and got delayed for release here?
Whats your hinge like ?
ddot what network are you on ?
same to you pizza65?
im on 02 , i dont think it is a network radio issue with switching of hspda/3g to 2g signals as it does say cell standby battery useage is around only 6% , but then again the phone could be false reporting

Not really if you want realistic real-world results with data connectivity etc. It varies too much since everything counts like signal strength.
You can always just turn off everything and burn the battery with a movie but first thing you should do is a few dozen full discharges before you do anything. I've noticed that HTC (and other manufacturers too) pre-use their batteries ie. charge and recharge them until they're optimal for consumers, hence the whine about bad batteries when people buy new phones (and in reviews as well).
I'm on Orange, I don't think its network because, as you confirmed, the "battery use" screen says that the screen is draining all the power. If nobody else gets a flicker on low brightness (it can take a few seconds to see it, but once you notice it...) then it looks like our screens are the culprit. Maybe.
I've deleted batterystats.bin and fully charged, so ill give that another chance before talking to play.
Ddot, what percentage of the drain is from the screen on your z? Also, if you press 'display' in that menu it will say how long the screen has been on, what does it say?
I have the same issue with battery performace. I've moved to Desire Z from my old Desire which had AMOLED display. On my old one, the display taked 5-8% of battery. On Desire Z I have minimum 50%, but ussually ~70%.
After reading that some people can use their DZs like "for two days of heavy use (gaming, browsing)" or "5% for 6 hours" I can't understand how?
Comparing to old Desire my DZ have poor battery performance. But the specs tells it must be much better.
I'll publish my battery usage stats after some days. Maybe it'll be useful.

Very interesting, thanks for sharing
And a really "geek" method here quoted from cyanogenmod issue:
Comment 27 by david.j.erickson, Aug 19, 2010
Now, I was still having abnormal drain on my battery. As suggested in the Wiki and also confirmed in another cyanogenmod post, clearing the battery stats can help. I followed this procedure:
Fully charge the battery, says Full and 100% under Settings - About phone - Status.
Reboot into recovery, wiped battery stats. Phone still plugged in at this point.
Reboot into rom, checked to make sure battery was still Full and 100%.
Unplugged phone.
Killed it, used Maps on Wifi and messing around. Killed it in about 3 hours or so.
Tried turning it on a couple times to make sure it was *dead* dead. It still tried to boot, but couldn't complete without shutting off.
Plugged phone in, booted it up. It may be better to not turn it on until it is fully charged, but this is just what I did.
Let it charge overnight, next morning took it off charger since it was full.
I have noticed pretty good battery life since doing this. This morning on my bus ride in I pretty much constantly played some Storm8 games and used Listen with Bluetooth, was only down to about 82 or 84%, can't remember. This is on par with previous CM release for me.
Not sure why this rom in particular had so much worse battery drain out of the gate, and not just for me. Fortunately it seems correctable. Maybe if a few of you could give this a try and see if it improves your battery performance we could conclusively say battery calibration is the solution.

What about the flicker? Can anyone confirm that?
I have a UK (read: QWERTY) Desire Z, first batch.
I tried reprodocuing the flicker by lowering the brightness completely and looking at a blank white page in the internet browser. Couldn't see it. Maybe I wasn't looking hard enough.
That said, I'm not getting the great battery life that most seem to be getting, and the stats always show the Display as being the number one drain. HOWEVER, it doesn't seem quite as bad as you guys are saying.
Right now, it looks like this:
Unplugged for 18 hours and 16 minutes, battery at 36%
Display accounts for 41% of the drain
It has been on for 50 minutes.
(stock ROM, running an IM client 24/7, synced to three email addresses... Typoclock seems to use 2% of the battery every time as well, which seems relatively high for such an innocuous little widget)
Yeah. I have some slight flickering too, slight when low light set.
Uk stock.
I dont think high display percent is an issue too much reading cyanogen issue comments.if you use nothing but low cpu burden apps, display should eat most.
Also if i have it off, power is eaten by cell standby.
Im still hoping for a settled battery log mentioned in forums.
My 2 cents:
If I "use" the phone, I have to plugin it every night.
If I do not "use" it (nobody calls that day, no browsing or GPS (Just work!)), I plugin it every two day (ex. mon - wed - fri).
The display is always 65-80 % of the "drain problem".
Today the stats are:
7.30 am: full chargerd 100%
7.30 pm: display drains: 70% in 1h : 21m - battery at 20%
I leave automatic background gmail sync on (only daylight, I use the "Flight mode" overnight)
No bluetooth, no wifi, no gps, brightness 35-40%

No phone either.
I'm on a North American Desire Z and I see the display using 70%-80% of the battery when I have the display on for approximately two hours out of the day. I keep my display quite dim too, at 20% brightness.
I'm also running everything stock. No root, no custom ROMs, no anything.
Isnt display percentage actually the display driver cpu time eaten?its just a theoretical value isnt it, not watts gone? It seems obvious that its eating a lot as it refreshes all the time regardless of display light level.
My screen on is only 33% today, im sure its usually higher though. Maybe its due to me flashing stuff all day. Ill do a full charge tonight and report back Sunday.

Hi
Had my phone a little over 24 hours and I may have a very poor battery
I have a LIVE screen on the one with the water and the leaves plus, I haven't made or received any calls but I have used it a little for internet and a few text messages
The green bar was on full about 5 hours ago and if I had to guess how long my use has been I would say 30 mins in total of the 5 hours, now my battery is indicating less than half full
Imagine if I was out all day making and receiving calls?
Does this sound normal?
This is normal for the first week or two , the battery is adjusting itself to your needs
Sent from my HTC Desire using XDA App
It's absolutely normal and you'll really notice a difference in about ten days, a couple of weeks the most.
That said, live wallpapers do use more battery. I much prefer a static dark one
adding to that make sure your phones nicely drained before recharging to ensure you get a nice full charge for next time... i took my desire's battery at least 5 days to start having a long term charge
bettery
same here took a week also what really helped me is having advanced task killer and setting it to kill unwanted apps after i lock the screen
i dont think you should use task killer, the apps will end them selves, i used task killer and got alot of force close after and errors etc
however force stopping unwanted applications is also good.
Android system 30%
cell standby 25%
phone idle 17%
android OS 15%
Display 11%
Internet 2%
5 H 55M 55S unplugged, hahaha no joke its all 5's
and now my battery is almost dead surely this cant be right
has anyone ever been given a replacement battery for their phone or do they ask for the phone to be returned if this is infact a fault
Battery sucks, phone is power hungry. Get used to it
I've had 2 desires since a week after it was released, i can count on one hand how many times I've got through a day without plugging my phone in.
I get about 2 days on my phone if I don't mess around with it a lot or get many calls. I normally plug it on overnight. Every night.
Nowadays that seems normal for a smartphone. Personally I think the battery life is slightly better than the iPhone 3GS.
Angry Birds means it lasts about 4-5 hours...

It's all down to how your using your phone. If you have a live wallpaper and many widgets and apps that run in the background like running in the notification bar, then yes, your phone will die pretty fast. Also it depends on how much CPU your burning. When I first got my Desire, I was like WTF. This is useless battery life and was starting to play hell. Now it's fine. I can leave it for 2 days easily if I just text or flick through settings. It just depends on what your running.
BTW, no one should have a task killer. It defeats the purpose of Android. You can get a lot of force closes and other things. Just leave them alone and let the OS handle the apps. Android does end the process if it's idle, eventually, but it's not using anything really other than a bit of memory just to keep it going a little.
As GoogleJelly pointed out, it really does depend on what you do with your phone and what's apps/processes are running on it while the device is using battery. Even I found the battery life pretty poor at the beginning...I found it quite annoying having to charge this thing nearly every day.
After some light tweaking, I managed to get the battery life to go over 3 days and I now have no reason to complain about my phone Mind you, I'm not a heavy user....As for background apps, I think i've got about 5/6 apps running at a time...
EDIT: I've attached a screenshot of my battery meter.....
What app are you using to view your battey history?
I also tested task killer when I got my phone. I thought it was fixing battery life, but after bedding the phone in a bit I took it off to see how much difference it would make and I didnt notice any difference at all...

I configured Quick Battery app to go to battery history from my phone settings every time I tap on it. You can view your battery history through:
Settings > About phone > Battery use.
If you want the graph, just tap on the top layer which shows the length of time you've been on battery.
EDIT: This works for Gingerbread based ROMs (it's the standard feature lol)...can't remember this being on Froyo.

This is irrelevant with Li-ion as this is a myth from the ages of NiMh batteries. Your battery will not get ruined if you don't discharge it completely before first charging.

Ah right, cheers for that. Didn't know it was all built in
One of the main reasons why new smartphone owners experience fast battery drain lies in the simple fact that they fill up seven homescreens with widgets that sync over mobile internet every hour or even more often, which really kills the poor juice like a massive gas leak.
After about half a year of use I've reached a stage where I use just 2 screens on my Desire (CM 6.1.1), of which page no2 is a full 4x5 agenda and Page one has just one actively updated widget (home weather).
Combined with restricting network usage of random apps by means of DroidWall and underclocking the processor at certain parameters (eg. battery <50%) the phone lives for 2 days pretty easily, with moderate browsing, music etc included.
But TBH I've really decided that the battery usage is absolutely random because some days it just drains like there's no tomorrow with no apparent reason that I've been able to identify. Carry a spare microUSB wire tbh :/
I read so much myths in this thread concerning Li-Ion batteries.
First of all Li-Ion batteries do have instantly the capacity they are intended for. Even 5 charges won't change that. The only thing which can change over time and charge-cycles is your phone recognizing a new voltage level as "full" (read more: "calibrating htc desire battery") or you playing less with the phone or having power-consuming apps uninstalled.
Also a full first charge is not necessary. This "requirement" are from past days with NiCd or NiMH battery-types.

The calibration during the initial week or so of using the phone arises from phone-side calibration, not the battery itself, which is why deleting battery stats from recovery can at times resolve battery issues :V
Phone didn't last half a day after flashing CM 6.1.1; after a couple of days I charged it to 100%, deleted the stats and voila, it's about as perfect as a terrible smartphone battery can get.
For the last 2 days my phone has completely lost its mind in term of battery.
Contant 1% per 10 minutes drain no matter the load.
Charging doesnt affect this at all.
Once my phone drops below 1% and turns off rebooting instantly brings it back to an exact 74% each time.
Factory reset doesnt fix it.
Most 3rd party apps show the same stats, Accubattery says that there is no usage information for proper calibration.
Thankfully its still under warranty, but it would take more than a week.
Is there any chance this is a software issue or should i just ship it back for repairs?
That looks very wrong and looks like a hardware problem. Did this occur over time, or right after you got your device?
Poco F3 easily holds 2 days on light usage, or 1,5 days with mid-heavy usage. Your graph looks very bad.
If AccuBattery isn't able to show information about your battery, that's also bad. Really looks like battery-failure or something related to it.
In terms of software, you'd have the possibility to flash the ROM (Android) again. However I don't think this would do anything. I don't think anything from the system could be corrupted in any way.
I think you should return it.

Ive had the phone for about 2 months and this is the first issue ive had with it( 2 days ag). No other issues other than the battery. no heat no crashes no restarts no nothing. battery life was brilliant.
I should also mention im running stock miui 12.5.3

I don't have anything in my mind that could potentially help you, other than reflashing the ROM. Reflashing would get rid of any potentially corrupt system files or configs and refresh the whole OS. But I don't know if this would help you.
I wish I could give you another tip but I can't think of anything. Did your phone fall maybe?

I've already done a factory reset. I dont recall anything happening to it recently. I removed my case to inspect for any bulging or cracks but everything looks pristine.
Well i guess its back to my oneplus 5 for a week.

hi, i have same problem. Is it solved? if yes, how you solved it?
Hello everyone, This is battery percentage graph of my 5 days old POCO F3. I believe screen is consuming way too much power in my device. Can you check it please? What do you think? Is it normal?
My display refresh rate is 120 Hz and auto brightness is enabled. MIUI 12.5.5, RKHMIXM

I couldn't tell you by looking at that how long do you think you get with video games on screen for 100 to 0 and how long browsing the web or light activities for screen on time?
It should be about 5 hours or so for games - I don't game so I can't confirm
8 hours or so for light activities. I can confirm 8 to 10 hours on light activities from personal experience
Also I use custom Android 12 aosp roms like evolution x
I do think stock does about the same.

The screen alone is consuming 1183.22 mAh for 5 hr 44 mins, while PUBG consumed 502.89 mAh for 45 mins of gameplay. I did play PES for 1 hour also. But the data shows exactly which app consumes how much. Here the screen is consuming 1183 mAh alone and the phone's battery is 4520 mAh.

Even if you are led to believe that these values are exact, they are not. Not at all. Android can only estimate the consumption.
Usually, Android can only read the voltage of the battery and then knows something like 4.2 volts = 100% = 4520 mAh, 3.7 volts = 0% = 0 mAh. All consumption values are then calculated from voltage drop and usage time.
It is not possible to determine the consumption of a single component or a single application exactly, since they never consume separately, but always together. Maybe there are a few inbuilt constants (like WiFi takes between -0.05 and -0.2 volts per hour or something), but the moment you play 3D games, so many components are demanded simultaneously and very differently that an exact determination is not possible.
TLDR: Don't care about the mAh.
As @Techguy777 said, 5 to 6 hours SOT while heavy gaming is quite reasonable.

Thanks for the explanation
I'm having the same problem with the battery. It charges to 31% e drains fast and when the phone reboots, it goes back to 31%.
Any infos on how to fix this? Maybe replacing the battery? If it's not the battery, what else could it be?
It's not the rom, the problem persist event on recovery and I already tried to flash different roms.
This issue already happened to my poco F3 three times. For first and second times i went to xioami service center to claim warranty repair. Its took a week or two to get back my device. For the third time happened recently and its too hassle for to claim warranty again coz the service center is too far. Read on other thread that the problem actually can be fix by reseating battery connector. But to do that will have me to open and put back the back cover. Its happened to remind me the old way, hard reboot. For the first time, i try press and hold power button for 15 sec an the device will rebooted couple of times but nothing change. Second try, i press and hold power button for 30, this time after finish booting the battery percentage info has changed but the charging and disharging info still problem. Then tried for third time press and hold power button for 45 second, this time all the battery issue for my phone have fixed. I suspected this happens when device in my pocket. The device accidently pressed some combination of key and when it reboot the issue happened.
