i have problem in my jasjar when the battery level reach 25% the jasjar switched off
and it doesnt work until i recharge the battery , any help please?
thanks
I had the same problem before don't buy any new battery its hardware problem. since mine was under warranty the shop changed according to them the motherboard and battery
I am having the same problem at 38 per cent.
Any solutions. I'm not sure I understand the second message.
Thanks.
when you load the battery everytime when its half empty, it developes a memory point then its says i am empty at 50%
on older batteries like ni/cad you have to drain the battery almost every time, by the newer batteries they say you dont need to empty them (li/ion etc)
for me even with li/ion batteries i drain my battery (not to 0%) every month or so. i think it keeps the battery life better. when you drain it to 0% (really empty) the battery can be broken sometimes.

I've brought my Desire Z back for reparation (Mainboard died and replaced by an official repair center).
I've bringed it with my stock Battery fully loaded (I took it from the charger and 30 minutes later it died). When i picked it up, the battery was totally empty. Nothing in it. The Phone didn't even turned on!
It taked a while on the charger, but finally it turned on and was charged to 100% in normal time.
Since that, I experience a huge battery drain. When I release my phone from the charger on 7.30AM, it is dead on 4.30PM with no use! No SMS, phonecall, nothing. Only Gmail sync.
I've tried different ROM's (With- and without sense) and did restore my phone to stock. It doesn't solve my problem, the drain still stays huge, even with no apps installed!!!
I've tried another battery > same problem!
What can this be? Normally, my Desire Z last about 1,5 days oder 2 days when nothing happens. Why it's draining so fast, even if it's not used?
What can I do to resolve this ??

try a new battery? Reset battery stats and give it a few days to actually get accurate readings? 8 hours isn't unheard of especially if your battery is giving up the ghost. give those thigns a try and maybe turn off sync and/or data to see if that makes a differance.

Thanks! I've already tried a new battery, but that makes no sense.
I'm now draining it to zero, i.e. when it's fully dead, and then charge it to 100% for 8 hours. When it's charged, i'll wipe battery stats. Let's see.
When anybody has more tips, i'm pleased to hear them!
Here's a tip: don't drain your battery to zero. This is a great way to shorten the life of the battery, or completely ruin it.
For purposes of battery meter calibration, draining to 10-20% is plenty sufficient.
There should be no problem draining a battery to zero as shown by software. There is a myth/misunderstanding that this is a bad thing because people confuse it with the fact that Lithium Ion batteries can be permanently damaged if they are drained too low.
BUT any device using such batteries will have its circuitry setup to have 0% set to a point above this damaging threshold.
So the "too low" point in hardware is likely to be below the zero point that the phone's firmware and software will let you go to.

x2 I concur with this. No need to fully discharge the battery, one it probably doesn't even fully discharge because I'm pretty sure the software is saving you from yourself, plus when the battery stats are uncalibrated I'm fairly certain it reads as discharged but in fact is only partially thus the calibration is off. Lastly I'm if the opinion that throwing different charge levels works better because it more closely resembles real life charging situations. Also letting it charge for that long does nothing because the phone charges only a trickle when full in order to not ruin the battery, similar to a laptop. Overcharge protection....
Thanks again!
Now I did charge it to full and wiped Battery stats.
After 1hour 30 minutes, it lost 10%. Did only send 2 short mails with Gmail.
Here is the usage chart:
- Screen 54% (Time active 4m 51s), Brightness ~20%
- Mobile Stand-By 20% (Time active 1u 26m 13s)
- Phone inactive 18% (Time Active 1u 21m 21s)
- Gmail 5% (CPU Total 31s, CPU Foreground 25s, enabled 51s)
- Android OS 3% (CPU Total 21s)
CPU is on idle ~10%, as always. I don't see any apps that are burning my battery.
s there something abnormal here?
just compared it with my statistics (running virtuous affinity)...
Mobile Stand-By seems to be very high... i have 4% (time active 2 h 30 m)
maybe radio related?

This stats come from Virtuous Affinity also. I'd had never had any problems with such a drain with my 'old phone'. As soon as I got it back from the repair center, the battery drain is huge.
I've reflashed the latest radio for my phone, made a Superwipe and made a fresh install of Viruous Affinity. Let's see.
I think that 'Cell Standby' is killing my battery. It is at the top of the usage list with 38% and it's all time active. My phone was left it's charger at 7.15AM, now at 9.00AM it lost 20% of it's battery on idle use only. On 9.00AM, I've turned my phone on airplane mode. Let's see if that works.
I will recover the phone to stock tonight. If this isn't working, I'll return the phone to the store.
Even with the phone on airplane mode the battery is heavily draining. My last escape is to remove the SD Card. If the draining continues, then I will bring my phone back.
Does the battery came hot? Like more than normal?
With temp+cpu app you can monitor your temperature.
Because if on idle the temperature's around 25-28 C, you should be alright.
And then you can consider what steviewevie said; lithium battery can be damaged if you go on a too low voltage. Even if the phone as his ''protection'' to not get the battery to a critical level, the battery can loose power even if its not used.
Lithium ion, its cool but not perfect.
Try a OEM brand new battery.

I've seen plenty of people on XDA with this phone and others that have rendered their battery unable to charge by letting it discharge to zero. Yes, there are failsafes meant to prevent over-discharge, but they apparently do not always work. The damage is not "permanent" in that its just the protection circuit of the battery kicking in. But the only way to bring the battery back from "sleeping" is with a special battery meter with boost function, which most people do not have access to. So for all practical purposes, its cheaper to just buy a new battery.
http://batteryuniversity.com/learn/article/low_voltage_cut_off
Yes, over-discharge will not LIKELY kill your battery in this way. But there is no point in taking the risk. The battery meter is far from accurate in the best of conditions. So there is zero benefit to letting the battery drain to zero, as opposed to 10 or 20 %, just for the benefit of calibrating the battery meter.
Also, even if over-discharge does not instantly "kill" the battery, running full cycles at the least will shorten the overall life of the battery. Its best to avoid full cycles and charge often.
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
Now this is just my experience from reading the experiences of others on XDA. I know there are hardware techs that can give much more first hand experience with batteries and may disagree. But as I figure, better safe than sorry. Especially when you consider there is no real benefit to letting it drain to zero on purpose.

The temp of the battery don't exceed 28 degrees, I test this with Battery Indicator Pro. When discharged, the Voltage is around 3,6 (Which is normal behaviour). When charged, it,s 4,2V which is normal also.
I have already tried a new battery, and it doesn't make sense. Same behaviour.
I'm really clueless, because it drains the battery always. Airplane mode an removal of the SD card makes no difference.
I will return to stock tonight, charge again, and see if it behaves the same. When yes, then I will return the phone as I don't accept such behaviour (Normally, my Battery last 30+ Hours on idle).
Thanks for your tips and help for so far! I will report.
I bought a new battery today, a Chinese knock-off battery which claims to have a capacity over 2000. I live in Mongolia, so that's basically my only option if I want a replacement battery, since there's basically no postal system here.
When I first put in the battery, it showed a 59% charge. After a few minutes and maybe a reboot, it showed a 20% charge. It consistently drained down to zero, and I'm charging it now.
I've experienced really strange battery drain with the former battery (also a Chinese knock-off) where it loses maybe 10 percent an hour on idle, so I figured the battery needs to be replaced. Is there anything I can do to calibrate it? I have a feeling that the charge is actually more than is being shown, but no way to confirm my suspicions. Am I right just to try to charge it to 100% and discharge it to 0% until the battery life gets better, or is there something else to do? I should mention I've tried resetting the battery stats in CWM with no real effect.
Thanks from Mongolia.
Go into recovery when battery is at 100% and go to advanced then clear battery stats or download battery config for rooted devices and clear battery stats that way.

Clearing battery stats achieves nothing other than deleting the stats on the what has been using battery power. Battery calibration isn't required on our phones.

if you want to increase battery life for your new battery, charge it fully to 100% whenever you charge it will increase charge storing capacity of the battery

Never, ever I repeat never let your battery drop below around 5%, and always charge it before it reaches zero. I use the Guage Battery widget v3 pro as it is very accurate, but you can also get the free version. You can & should use the free battery calibration tool from the Google play store, simply install it & charge the battery to 100% then run the calibration App. simples

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 bought HTC One X(international) a week ago,and have a question about the battery calibration,when I unpacked the phone it had battery on around 50% then I used it until first battery low on power notice,I think it's about 15% battery I don't remember,then I let it fully charged,and my phone goes for about a little less than 2 days on standby with 15min calls,some music,games a little,but mobile data is always off so is wifi,i only turn them on when I actually need the internet connection,for web browsing,now my question is, is my battery properly calibrated,because I have read that you have to fully charge the battery before first use(that I didn't do,but when I put it on charger I didn't disconnect it until full charge),so that system could record battery capacity,otherwise it will record incorrect battery capacity,and battery will last shorter than it has to last,I supose it will record incorrectly,battery full notice,and will notice that battery is full to early thus resulting in shorter battery life,now knowing my use of the phone,can it last longer,and do I need to re calibrate the battery?
There is no such thing as battery calibration. Your battery will be fine, nothing needs doing.
tl;dr: Got a new battery. I've seen lots of posts around on how to reset the battery stats so the phone "knows" how to accurately gauge how much batter is left. Is that necessary with a new battery?
I upgraded to stock pie about a month or so ago. Since then, my phone randomly freezes and reboots 5-10 times per day. It's not an app causing it as it does it the same thing in safe mode. It happens when the phone is plugged in also. I thought maybe it was the battery, so I got a new one installed. It's still doing it even after the new battery. I've seen lots of posts around on how to reset the battery stats so the phone "knows" how to accurately gauge how much batter is left. Is that necessary with a new battery?
What Is your screen on time with the new battery? do you recomend replace the battery?
Jumping in, 6 months old device, battery still has full capacity.

I don't really remember what it was before I had the battery replaced. SOT was definitely quite a bit lower than when new. The phone was over a year and half old and I'm a pretty heavy user so it was charge cycles A LOT. IIRC, Accubattery showed it was holding about 75% of original charge. It definitely feels, like the new battery as a couple more(if not more) hours of SOT now.

Hi there.
Was wondering if u have replaced the battery yourself. And it survived the procedure alright. I am now having the same stats - accubattery shows 75% health.
Should I go for it? Scared as hell
