Battery indicator inaccurate boost, anyone else with this problem?

My battery indicator (in status bar) likes to increase each time I restart my device. Does anyone else have this issue?
I am charging and the indication shows as charging plus the percentage is increasing like normal. However, when I restart the device it shows more than charge percent. For instance, show 56 % but after restart device shows 82 or more than 92. Thank a lot in advance for taking your time to reply
I've tried searching to see if it's a common problem, but I haven't been able to find others with the same issue with Artemis
My Rom: Touch_4.02_Vanilla

I've the same issue, and I guess its normal.

hmmmm...well..for past one year...i have my 100% battery accuracy.
Have you noticed when charging its getting charge slowly and draining is also extremely fast after restart because its showing more than whats charged.. Maybe i guess its my battery got screwed up

...
its a common battery problem with the artemis/p3300
leave device off while your charging though

Thanks dude for the reply.....relieved to know that its not my device nor rom....else I would be spending time trying to flash roms and roms.....till i buy another battery Ill stick to ur tip ' Device Off While Charging"

[Q] Battery...

hello there,
few month ago i updated my xperia arc to 2.3.4, rooted it and almost everything works fine,
exept a strange battery problem...
everytime i fully charge my phone and boot it up, it seems that the boot process needs round about 2-7 % of the battery.
after the boot i check the battery and its not fully charged (mostly 96%),
also the battery drain is really massive, every minute i use the phone it drops like 2-3 %.
any thoughts?
also, is there a new firmware already?
thanks

Well its battery drain issue..
On .42 fw..
Umm, what about your usage?
Do u use so many apps?
About the boot,
When u boot and the battery is not 100%,
Charge it again until 100%,
Turn off, take off your battery for 10 seconds,
And then turn on, charge again till 100%,
Repeat the steps until you got 100% when u boot ur phone.
It works for me, maybe works too for you.

Xperia Arc Battery Issue (Official ICS ROM)

From the past one month or so I am having this weird issue with my phone's battery. The battery drops straight from 20% to 1% and the phone switches off. This last time, I connected the charger before the phone switched off ( a matter of few seconds ) and the battery jumped straight to 21%. Is my battery terminally damaged or is it a software issue? I have attached a screenshot of the battery discharge graph available in settings menu.
Also, I faced the insufficient memory problem and I have repaired the phone about 2 months back using PC companion to ICS 4.0.4. I have been using the phone for about 15 months as of today.
Thanks.

hmmm maybe you charge your phone from pc? if you do this the battery will never get fully charged really...that i can say from my personal experiance.
By the way just charge the phone as much you can also let it charge on 100% and reboot it(battery lvl must go lower than 100) do this till you get a reboot with 100%...
If those do not help your battery is damaged you maybe have banding issues,3g/wrong baseband,forground apps? maybe a combo of all this.

Had the same issue, cured after repairing on SEUS.

Quite a fluctuate on the graph.

Maybe try to recalibrate battery!

Same issue, on mk16a. The battery is weird, if I leave CWM running it last for more than one hour, but androids jumps from 20% 1% or 0% suddenly. Also when booting again (after the shutdown) it's reports 20% but again it drops...
I'm on CM10 but i think this happens also on stock ICS.
Battery calibration don't work...tested it 2 times
Any hints?

battery weird fail/very fast discharge

Hey all,
I have the wildfire running with a stable CM nightly (forgot exact version, but already a good year old I think and never any problem with the battery). I have not recently done anything special with my phone (no new radio, ROM, updates, new apps, ...) but since a week or two I have the following problem:
Charging the phone takes first of all ages to reach 100%. And when it's charged, it will crash about 4 hours later. The battery indicator will be at about 35% or higher just before it crashes (thus not at 0). When I reboot (while charging after the crash) however, it says 0 or 1% left. When I then go to the settings -> about phone -> battery , the battery life just INSTANTLY drops from about 60% to zero (see picture)
This problem appeared pretty out of nowhere. Is this a battery calibration problem, or do you guys think the battery is just at the end of its life? I'm aware that this could just be it since the phone is almost 3 years old (bought on day of release here), but it's just acting so strange.
Any help is appreciated,
Thanks,
Maarten

Try the two obvious things
1- wipe dalvik cache and cache partition
2-wipe battery stats
Can you post a screenshot os the battery usage screen

The level indicator is in the first post, the usage (apps etc) I cannot do right now as after wiping it does not reboot anymore (stuck at HTC screen), but it was about 50% for signal and 50% for standby (or what are the 2 largest users in %, I forgot)

Wipe battery stats or manually delete batterystats.bin. Calibrate it. If nothing works reflash your rom. Not a battery prob.

Odp: battery weird fail/very fast discharge
I had similar situation. Change battery. It is broken probably.

There seems to be many battery problems for wildfire, I had to abandon mine because of a similar problem, except it would charge to 100% but then drop to 4% within a few hours and wiping battery cache never helped, tried my battery in another wildfire no problems so in the end I gave up with it
But I remember someone saying it was something damaged inside the phone
Anyway good look with your issue hope it gets solved.

I fixed my booting problem by reflashing the ROM. I also wiped cache/dalvik and battery stats.
The problem remains however. Stays around 100 pretty long, then goes to 80% in less than an hour. And then it crashed around something like 60%. After rebooting it said 34% left.
Guess the only thing else I can try is to completely empty the battery, then recharge it whilst the phone is off.
I'm going to buy a new smartphone soon, so it better just work another month !

Yea, wipe battery stats again, sue ur phone till its 0% and charge up to 100%, keep on charging for about 20 mins.. try then if battery shoes properly..

Doesn't seem to solve it... Completely emptied the battery (or at least I'd think it is empty, see further), then charged for like 8 hours whilst phone is off, then wiped battery stats in recovery. Then after rebooting first thing it did was crashing again.
The crashes often seem to be related with internet/apps. I now have internet and poweramp app off and it works fine (no crashes), but when I turn these on, sometimes after a minute it crashes, pretty weird
Also after some crashes, about 15 minutes later I can suddenly reboot, then it showed 15%, then it crashed again. After reboot (without any charging) it showed 65%... The indicator is completely ****ed up it seems...
Guess there is nothing to do but getting a new phone as this is too annoying. Thanks for the help though !

Batt voltage meter defect
I have a exacly same problem.
It is the voltage meter problem. Mine wildy shows 4.07V at fully charged battery which if you measure conected battery on its terminals mulitimiter shows 4.273 so its off by 0.2V. Now the phone will never light green led, it think battery is not charged fully. I checek this with 4 years old and new original htc batts. Same thing, voltage meter defect! If you charge it to full, multimeter shows 4.237V on batt terminals,reboot it and get a spike to 92% it suddenly drops to 78% even though mains charger is still connected and charging! Internal Volt meter also reads dorp from 4.07 to 4.02! :crying:
There i also thread on Desire Z forums of same thing happening here.
Is this HTC using crappy mobo components?

Htc wildfire is no more released now. It stopped in 2010. This has the answer. That is one of the bug with wildfire.

[Q] Battery Just Drops!!

hello everyone ....
i've had this problem for like a month now
the battery works normally untill it gets to 22-20% then it suddenly drops to 5% or so...
then it drops again to 1% when it might stay at 1% for like 1 hour of so.....or sometimes it just shutsdown but when i plug the charger the % gets right back to 20-23% in a second and then charges normally!!
thanks in advance to everyone who would try to help me
i'm using the 3g version btw
