Hi, I have a problem with the battery of my htc one A9, in practice since it lasted a few hours now, I replaced it with a new one. The problem is that the new battery should be calibrated correctly for the phone to correctly recognize the life of the new battery. I tried to calibrate it by following some methods that there are online such as having the phone completely discharged to zero, recharge, after it has charged, leave it still charging for another 2 hours and then unplug ... wait 10 minutes and then plug the cable again and turn the phone back on and then unplug the cable .... there are several variations, I tried them all but I haven't solved it ... on the contrary I noticed that every time I did get to zero the battery lasted less and less .... the first once I downloaded it to zero, it continued for about 2 hours of autonomy with an active movie .... then as I did these tests downloading it to zero (done about 3-4 times) I noticed that after it reached the zero lasted less and less to turn off ... and the duration from 100% to 0 was always the same ... so in practice it was evident that the battery was being damaged by discharging it to zero .. I used the Accubattery app which tells the status of battery health and gave me 59% so very bad .. let's say s what I had with the old battery .. The new battery was produced in September 2015 I tried to buy another new battery with production date of September 2016 (unfortunately it is impossible to find original batteries with a + recent production date), as well as in the first one the battery suddenly goes out at 30-40% ... with accubattery even gives me a percentage of 31% as a state of health ... you understand that it is bad and you have to calibrate it ... but I have not tried the methods I did with the other previous battery since they were useless, indeed they damaged the battery discharging it to zero ... Now I would like to ask you surely some of you will have changed the battery in this smartphone, how did you do to calibrate it correctly so that the android system correctly recognizes that the battery is new and therefore has a different duration? do you think the calibration problem is solved by restoring the system? ... I hope someone can help me because I only spent money buying batteries and equipment to open the phone without solving the problem indeed it is even worse than before ... Doing the system restore is not a trivial thing, so before doing it I would like some reassurance that so I can solve the problem .. if maybe someone has tried. I'm definitely not the only one who replaced the battery in this phone so I hope someone can help me fix it. let me know how you solved it. Thanks a lot to those who want to help me.

Maybe this depends on the batterys but mine was having that problem of going dead at higher and higher % it started at 10 than 30 then 50 and up to 70 I think.
I've tested all the solutions in the wiki (yes the freezer too ) but with no improvements, then I did the opposite, instead of draining the battery fast I drained the battery slowly and when the Universal shuted off I pluged it to the electricity until it boots ok and the cpu returned to 0/1%, then take it from electric power again and wait until it goes dead again and did this over and over again until I reached the minimum battery of 9% i think. Great improvement since I was already looking for battery replacements... Then I charged it over night.
Conclusion I have the Universal alive for 3 consecutive days (and nights) now at 52% waiting to check when it dies again
By draining the battery slowly I mean no light in the screen, no running programs and universal in closed state, flight mode and just one thing to check if it was alive or not, play some music in WMP in repeat mode, when it stoped playing it was time to have a litte more eletric juice until I could boot it up and start the music playing again.
When I have the final results -> when the universal goes down I will post the solution in the wiki
Again this may depend on the batterys but since there are so many people buying new ones you maybe want to try this solution too.
Oh and by the way I solved an "other" problem while trying to solve this...
Besides the tests on the battery like freezing it over night, taking the power level pin etc, I've started to think it was a problem from the rom so I cleaned the Universal doing that "task 28" thing and the result was solving the problem that I was having with the battery status (now home screen plus plus) it was not getting the cpu using percentage when in the past it did. Now with the cleaning reg whatever It is showing again the cpu using %
I don't know if you use this but it has a cool functionality, posting the cpu using % at the top bar of your universal can tell you how much the universal is working all the time, enabling you to notice when it is working when it shouldn't, normally some stupid background program that didn't go off...
hi there. I have two same unis, and three batteries. two standard, one big capacity 3200mAh (personally I dont believe it have such capacity, it is some china crap). but all three had that issue (uni shut down when capacity still showing more as 30% or more %). tried to deplete the battery completely (when it wont boot, I put device to bootloader mode and wait untill died completelly). now it show again 0% on all three batteries. I dont want to say, that your method is bad . no, I am just a lucky one, where the "wiki" methods worked correctly. and I think it is also important sometime charge the battery completelly, not only for couple of minutes, but until you see green light. when you deplete the battery completelly to zero (it is never zero, electronics integrated on the batter doesnt allow that) charging to full take much more time as before.
powerdetect
one more thing, you can test, how much capacity your battery have. it is simple utility called power detect. you can find it in THIS thread or as attached file. just copy to device and run. the test will suspend itself after one hour, so set all settings as needed. it will automatically create file, where you can find all important information. before you use it first time, charge your battery to full.
Thank you for the reply, My battery still dies at 30% but no more at 70% and 50% and it lasts 3 days/nights in a row.
I tried the boot loader mode but it seemed it had a timeout, instead of dying from battery losse it died from some kind of time out :/ because I was still capable of juicing some more battery if i went again to boot loader...
I will check that app, thnks again
wat i did..
well my battery used to shut off at 95 above present...wat i did was drain the battery with a 12 volt motor, took me a complete day for it to discharge, then i put it in the freezer, was suppose to put it for one night but i actually forgot bout me putting the battery in the freezer n i remembered after 2 days. then i charged it which also took around 18 hours to charge now my batter shouts itself at 70% n i can listen to music for 1.5 hours. which is a lot from a battery which was shutting at 95%
I have 2 SPVC600 phones and one is not even 24 hours in standby before the battery goes empty, whereas the other phone is in standby several days. I tried several different "virgin" ROMs on both phones, several different batteries, still the same problem, one phone just sucks the energy out of the battery like crazy.
Anybody knows where the problem is and how it could be fixed?
Thanks

Same Here...
Hi, i know that this is a old thread, but... the same issue here, i have a T-mobile SDA, replace the original battery that come with the phone 2 years ago, this battery die and ebay a fresh battery again, but... nothing, goes empty in less than 13 hours with the fresh and new battery (with the old one at least 4 hours before die under nitrogen´s wm6 rom), any suggestion? (i clean the phone of programs, change roms, downgrade to original WM5 but... nothing, only 12 to 14 hours and empty ), the new battery is a "OEM ST26" from sanyo...
Until this day, my tornado was the more reliable and trust phone that i´ve had
Can you recommend me any procedure for test the phone... do you think that is a usb connection Issue, i read in a lot of threads that this could be Rom upgrade... ´coz the new drivers, componets, etc.... any help ir really appreciated
Greetings from Colombia...
Usually the original batteries are the best you can get. Even the (now very old) original ones (Sanyo ST26-C) still have their original capacity and I have not seen a single battery of these that has failed until now.
If you see such a drain from the device you could possibly disassemble the device and clean it. If that does not help - sad :-(
Does it make difference if you charge the battery on the device being off or while OS is running?
If you have volt-meter: what is th battery-voltage when empty/fully loaded?
Hi Tobbie, thanks for the reply, yeah, i follow all procedures for battery maintance, i try charge with the phone off, phone on (with radio turned on and off, really i only see a difference of only 1 1/2 hours...), this night i try clean with isopropilic alcohol the contacs between battery an phone and i see... i noted something peculiar:sometimes when i plug the AC Adapter or connecting to my desktop, the led indicator (in this case orange), dont turn on, sometime this led appars and dissapear passing 20 seconds but full charge the phone (i see this in seetings=> energy configuration => 100%)... other times this light is hold until this change to green (fully charged), but ever the same result, lees than 12 Hours... this happen with both batteries (old one and fresh buyed from a reliable seller 15 days ago...)
I download awhile the service manual for tornado but... Scare... i really love this phone, really i have now a LG Incite, but this phone is my "backup", coz all time buy and sell phones, but this since 2005 "sleep with me...", if after clean contacts i dont see any change or fix... No mercy with tornado´s LOL...
and i want with all neighborhoods a voltimeter, can you tell me about the standar values for this battery (my knowlodgement about electronics are limited a lot), i post my results here after my test...)
Thanks a lot, i hope that you can help me later (and sorry for my ugly english)
Greetings from Colombia
This sounds weird, but the only reasonable source of evil is that also your other battery (equally aged, but unused probably) is chemically dead. It hardly ever happens that the charge-electronics is going mad somehow. With the many Tornado that I had on my desk, not a single one had problems with this part. For some devices I have seen that the batteries were stone dead - and these behave as you describe it.
It looks as if the battery has lost its capacity. A fully charged battery has a capacity of roughly 1100 mAh. With a drain of ~75mA (for the fully lit display) this will last 14h and 40 minutes. So a similar power drain would have to suck the juice off the battery - which I doubt that anything will do. If you switched off all radio parts (GSM, WLAN + BT) there is nothing left that drains the battery like this.
You could try to check how long the batteries will last when you have the display light draining the battery additionally. For this part it is well known how much it drains (see above) - and if you see that the battery lasts half the time of what you said before - then the battery is ok and the device has some mysterious power drain. If however the battery only lasts a few minutes with this defined load - then it is surely dead.
Check the battery capacity link in my signature to get the tooling for measuring this easily.
Voltages should be measured with a digital Voltmeter if you have access to one. They are for dead batteries not much different to good ones if you do not apply load, but a fully charged LiIon has around 4,2 V and discharged in a Tornado around 3,55 V.
The Tornado will shut off at around 3,55 V but if the Voltage is much higher when removing the battery and measuring the Voltage - another hint for a dead battery.
Good luck
I know there are a few threads on the battery levels being a bit random at times, but mine is really hacking me off.
It will stop at say 75% and just stay there, when I reboot its down to like 50% or less. Twice now its gone dead because I though it had plenty of charge but just wasn't moving.
Is it the phone or battery thats the problem or drivers or something - ps this is on a standard rom, no tweaks etc.
same here.im using romeos rom but it seems to be a problem with another roms to.the battery % stay (for example) 10 hrs 68 % and after reset dropt 5,10,15 % down . is it hardware problem or software ?
And quite same here... The case is a bit worse even. When I charge it from lo-bat warning to full, it sort of overcharges itself and might hang up even! I noticed this in two phases - 1) when I left my TP to charge during night, it was hanged in the morning 2) when charging from lo-batt and restarting at ~85% bat level, after boot up the battery reports something at 98% or something!
I have the same (all posts) some time I have 78% and make reset and now i have 89%. Which is real 78 or 89%!??
when I charge all night I have only 70-92% after 6 hours, and after reset 100%
For me this is unusable as I cant trust it without constantly rebooting which is not good enough.
Lucky for me its a second phone, so I'll flog it and think of something else.
Hi there!
I have the same problem, after charging over night. The battery indicator shows, that a battery is not fully charged. After short removing battery and rebooting it shows 100%. With another HTC battery it is the same. When I use another spare battery (not original HTC), it works correctly. But I dont like the spare battery, because it is hard to remove from device because of its sharp edges. I think, it is a HW problem of battery, or a problem of device.
Hi guys
I should be picking up my SGS2 today and I was just wondering what exactly I should be doing with the battery? I've read in a bunch of places that draining the battery fully and then recharging it fully gives better battery life, but I've also read this:
Lithium ion batteries do not respond well to full discharge, you will see reduced capacity and early failure if it happens too often. In any case it is not possible to overcharge the battery on a BlackBerry because the battery and phone have enough intelligence to control the charge (unless the battery is already defective).

(this is from crackberry.com but you get the idea)
What's the best thing to do?
And on Android phones, when the battery indicator shows 20% or something, is that when the phone is going to die? Or will it die at 0%? Obviously at 20% it would be to protect the battery but maybe Android has been programmed to show 0% when the battery is actually at 20%.
Thanks,
Elliott
read manuals !!!!!! You can see this
Did not receive an owners manual with my phone. Anyway...phone is charging now so too late I guess...

The manual is probably stored on the phone, at least my new Ascend II came with its stored on the phone, you have to goto the big menu (forgive me for not knowing the technical term for it) to find it however
i got my battery fully charged...then in the first day i discharged it till 10% at least that's what my phone was saying
i read too that the new li-ion batteryes do not need to be "formated" (fully discharged till the phone dies and then fully charged with the phone turned off) in android case i think that thing is not posible coz it needs at least 5% to pass the bootloader and then begin to charge
anyway in my manual it says that the battery will begin the normal state after 8 days of use, until then it may disschage quick
i have a motorola defy
Calibrate the battery. Charge the phone while its switched off for about 6 hours, and then use the phone untill the entire battery runs out and it switches off on its own. After this, the phone should be able to use the battery properly.
i just used my galaxy and made it empty, then charged it full.
nowadays i have runtimes from 3days (72 hours) and then its @ about 5%
there seems to be a lot of back-and-forth regarding whether or not draining a battery is healthy; i drain my iphone battery down to zero about once a month and the battery has been doing fine for two years . . . whether it would be doing just as well without the draining time is anyone's guess.
I have always been under the impression that lit-ion batteries do not need any kind of special care or break in. But since our phones estimate the charge, we should occasionally let the battery run out to reset the calibration in case it gets screwed up.

I don't think you need to worry about draining the battery till it's dead. My phone dies often and the battery is still kickin It's my understanding, that the purpose of draining the phone before you charge it is to calibrate what the OS says for charge remaining to the battery's actual charge.
Or something like that...
Hi all,
I have my sgs 2 since June and it's working pretty well apart from the battery drain which is very harmful in my daily life
I've recently flashed the Cognition 1.30 (last friday). Before that, my sgs was able to last the entire day before discharging with a moderate use (10-20 mn on games, few sms, 15 mn consulting mails, 1 hr on internet). Since i've flashed with the cognition Rom, the battery drain is really awesome!!!!!!
I fully charge the phone (switched off) then when i switch it on and the phone stays idle, after 1 hr or so, i've already lost almost 20%. When i'm on internet or playing games, the battery loss is approximatively of 1% per min.
I've made a full wipe and recalibrated my battery so normally it should at least last a day and thats not the case.
Could somebody help me or should i buy a new battery and test it ?
Because i relly like this rom and from others users, it has a good feedback concerning the battery use
Hey guys I am a long time Android enthusiast. I have one of the most popular Samsung devices which is the Samsung Galaxy fit. The problem with my Samsung Galaxy Fit is the battery. Earlier before any tweaking battery used to be normal. After I installed CM7(official build). My battery started draining randomly. At first it was ignorable but then the problem became severe. From 100% it would drop to 88% in just 2 mins use and then from 88% it wud drop to 70% in another 5 mins and the entire phone would be dead in just 3 hours at best. When I would charge the phone again the battery will also be charged randomly going from 5% to 20% and then 20% to 40% all this in just 10 mins. In no less than 20 mins would my phone be 100% charged but that's fake as the battery would drain from 100% to 0% in three hours.
Following are the solutions are tried
Changed the batter,used a brand new original battery(FAIL - DID NOT WORK)
Flashed stock Rom (FAIL - PROBLEM STILL PERSISTS)
Changed Charger (FAIL)
Recharged battery on a different phone and then inserted the battery in fit (FAIL)
If anyone has any solution please let me know. I AM ALSO WILLING TO DONATE IF PROBLEM GETS SOLVED.

You could try Battery Calibrator.. The app is available on Play Store.

Hope this will help you..
1. after flashing custom ROMS, back to recovery or CWM then wipe the battery stats.
2. calibrate the battery while device is on, i ussually use Mugen Power app (install app, choose the standard battery, charge until 100% then click calibrate, after that use the device until the phone is dead then charge until 100% again while device is off).
other Calibration apps ussually have the same steps like the steps i mentioned above, so just use one app..
3. if you still having the battery drain, maybe you should go check the hardware in some technician, coz it could be the hardware that has the problems.
