Battery drain... funny problem

Hi All,
Got this funny problem since I have flashed TNT WM6.1.
My mobile battery shows some funny traits.
1. It can suddenly go off (even if the bar is at 87% or 63% or 30% or anything of that sort)
2. Once it goes off, it gets into a loopback of restarting the device, goes upto the screen where WM6.1 logo appears and restarts again.
3. The only way I can then get it restarted is to get it to plug to a powersource.
4. When I plugin it shows within 5 min that the battery is fully charged.
5. I use audio manager a lot and its like every 30 seconds 1% of battery is gone.
Have search through the forum but haven't found anything like this.
Anyone has face a similar problem and found any solution?
Any help will be much appreciated.
I am on SPL/IPL 3.08.

Time for a new battery....
I ran across the same problem. It turned out that the terminals on the battery were seriously worn down so much that the battery couldn't hold a charge to safe it's life let alone mine!!!! I went to a battery store and replaced the muthaf^$#a!!!!!
Go grab a new battery and you'll be electric sliding again in no time!!!!

Thanks Trej3k. Much appreciate your response.

Yeah
Had the same issue.
Replaced the battery ... and now everything is fine.
Now I don't expect 5 days without recharge but at least 2 days.
Along with the new battery I bought an battery charger so now I can use two batteries.
The nice thing is that the old battery is lasting at least as the new one, Maybe because of the charging more regularly and not so frequently and because both batteries never go in usage when they are hot of charge.
Try your thing

I had the same problem pretty soon after I flashed my ROM for the first time. I would charge to 100% and then browse the Internet or take a call, and the device would reset within a couple of minutes b/c it would think it was out of power. The timing may have been a coincidence; I don't know. I bought an extended battery and everything works fine now.

I had the exact same problem right after flashing to wm6. I really wonder if it's a coincidence.

I ordered a new battery today because I have exactly the same problem. I also apeared after flashing WM6.1 a while ago an became worse with time. Since my battery is 3 years old, it could also just be a battery at its end of life...

2250mAh battery - not performing good!

I purchased a new 2250mAh extended battery recently from megacapacity.com.
In a full charge it gives me 18-20 hours backup with 1 hr talk time only. I don't even use Wi-Fi, GPRS. Just simple calls.
Is it normal? i dont think. Original battery 1050mAh gave better performance when it was in good condition. What could be the issue?
I have tried almost every ROM but its almost same in every case.
Anybody having 2250mAh battery? pl share your thoughts.
Is there some problem with device not charging optimally or battery is bad?

2250
I have a 2250 battery purchased from megacapacity itself. The first charge lasted for 50 hours. The battery at the time of recharge was around 20% but I recharged again. I am sure it would have gone for another 10 hours at least.
This is with moderate calls, browsing, solitaire, always on Microsoft Push mail and lot of email reading and writing. I was basically testing the battery backup; so kind of stressed my phone a bit to see the actual backup time available.
On a related note, I was definitely not happy with megacapacity as they didn't send me the correct battery cover for vox and never responded to any of my emails. So now my phone is without battery cover. And I am planning to buy one more normal sized battery because of this. Thanks to megacapacity.
Sankar
PS: - I am using fireburned 6.1 stable rom 1.4.

I am pretty happy with Polar CEll 1300 mAh battery. It gets me through the day with heavy use! It dies when I am IMing over Wifi for a couple of hours in the evening.

Is it device charging issue?
My device was also working good with original battery. I used it for approx 18 months. After that (couple of months back) it started giving problem shutting down device suddenly while in the call. Its calibration was totally disturbed, i happend due to high temperatures some time when in car, i think so.
In nutshell that battery was of no use to be thrown out. Then,
I bought 2250 mAh but its not giving expected performance, its lasts for max one day with normal use.
Could it be due to issues with device charging circuit? It gets charged fully in one hour. i suspect there might be some issue with device circuit.
or finally battery is not good?
Pl advise.

parthabhatta & h4waii,
You both have good experince with VOX battery, pl share your thoughts on this.

Hi,
Actually I use a battery bought from megacapacity but its 1100mAh. The battery is not giving me any problems and after a few calls, roughly one hour surfing and some music playing 20-30% battery is still left. So what I feel is being 2250mAh it should last atleast 80% more than 1100 mAh if not double. You can check the Power management battery bar while charging - whether it shoots up occassionally at random or gradually increases with increments of 1% till it attains 100%. If it shoots up, try with USB charging and see if the problem recurs. Give it a try and let us know.

Just be careful of using BIG battery.

Thats a good idea, sure i will check and let you know.

I charged my 2250mAH in an external charger, which removes any possibility of the device shutting off charge after it reaches a certain voltage. It allows the battery to make that choice. I had good use with it, very heavy usage and it would last drastically longer than the OEM 1100mAH unit. I'd recommend just buying a 1300mAH as the 2250 is very cumbersome to carry around on the device.
Again, I still have mine - if anybody wants to buy them.
There are a few issues with keeping the sheet in contact with the pins, else it will shut off randomly, I padded it with paper and pulled the pins out a bit.

i got mine a year ago from ebaystore dmc-batteries.
first i also got the wrong backcover, but they sent me very fast the correct one.
The battery is definitely not twice as strong as the original one.
At normal use I think the max is 1,5 day. Light use gives me 2 days but heavy use with bluetooth or wifi or gprs only 1 day.
as h4waii I had in the beginning some problems with the contacts and sudden loss of power because of that, but that disappeared with time

Still I can't make a point...I'cant determine were is good to buy (obviously referring xda user's opinion to how much the battery lasts) and where is better not to buy. LoL

dmc-batteries gave me good service and are quick and friendy in their replies. I recommend them.

Thank you birdibird , but my intention was a survey to know what brand (seller) of ezxtended battery lasts more than an other. Just that
Because I've read of battery lasting 4-5 days with normal usage and others not lasting more than 1!

[Q] Battery recalibration issues - G1 on CM 5.0.8

My apologies if I am here with the same complaint, but I tried searching this forum and found nothing that works for me.
Basically, I rooted and flashed CM 5.0.8 and I have been having battery issues. Now its not that my device is draining battery at a very fast rate (seems it is indeed doing that), but I suspect there is some problem with the battery meter.
So from all the stuff that I read, I decided to recalibrate the battery. I charged it up to full, until the green light went off, until the status showed 100%(full) and then some more. I then restarted into recovery(Amon-RA 1.7.0) and wiped the battery stats and rebooted back into CM, while having the charger connected at all times. Its worth noting however that during the time the phone was booting itself into recovery or into the ROM itself, the charging indicator stayed off. Thanks to that, when the phone booted into CM, the indicator was red for a few mins before it turned green (charge had dropped 99%)
Now I've done this 2-3 times, including letting the phone die due to an empty battery, but I am still getting very little life from the phone. For the record, I have the end button set to sleep and I don't have any continuously running widgets and my syncing apps (twitter) are set to sync only every 1 hour.
Anyway, again I don't think these apps are draining much battery, since once the battery dies down and the phone switches off (after light to moderate usage as compared to the life 1.6 Donut gave me), when I put it back to charge and turn the phone on after 5-10 mins of charge (while the phone is off), the meter shows a charge level of around 65%. So I suspect that the battery charge is at around 50-60% during when the meter reads it as around 1% and forces the phone to turn off.
I also tried switching on the phone after it had turned off, but it switches off immediately after booting (at least on 1.6, I could reboot it a couple of time on a 'dead' battery)
Are there any other tips that I can use to recalib my battery? Any idea will be much appreciated as my phone dies out each day before I can get back home and put it on the plug. Should I consider upgrading to CM6-RC1? Has it been proven that the battery performance is better on that?

Have u tried swapping out the battery with another one to isolate it to possibly the battery itself? Isolation is key, that way could it be ur extusb isn't charging correctly or is it the battery?

Well, I do have a spare - the one I saved from my bricked G1, but I haven't tried it out yet. The battery was working perfectly well just a few days ago when I had a stock Donut. So, I suppose it isn't a battery problem, but no harm in trying out the other one.

i had issues with my lithion battery and found out it happened to be on its last breathe. And with my spare i had it worked good. did u drop the battery at all? with lithium ion batteries can be as delicate as expensive china or porcelain. And to be honest the batteries that came with our g1's aren't really that good. If you can I would suggest getting an ext. battery from ebay. ive heard that fully discharging a lithion battery isn't the best practice either. I'm no expert just experience Best of Luck!

well...
reading the Cyanogen 5 thread I noticed at least 5 people with a broken battery...
for the record mine is broken too...
it's all swollen up... I mean, I can use it but it doesn't last a full day and it doesn't fit perfectly anymore in its slot inside the phone...
I'm starting to think that maybe for some reason flashing cyanogen 5 caused this issue, since so many people had this problem at the same time...
or maybe it's just a time defect of some stock htc batteries... who knows...

@GigiSpligi: Nono... don't blame CM for the swollen battery. Batteries tend to swell up after a lot of usage (charge discharge cycles). The battery on my old Nokia phone had swollen up after about 2 years of use. Similarly my friends E51 battery. Also my G1 batt seems to have swollen a little bit already. So nothing to do with the ROM.
Of course, if the ROM is making you charge frequently, then it is indirectly causing the effect on the battery.

The exact same thing happened to me ... actually on all ROMs now ... i'm gonna look into getting a new battery and sdcard which kinda sucks, but oh well. when i think about it, i wasn't have any problems till i started flashing sense based ROMs, especially Slide ROMs. so i must have done something wrong. i can't even make a phone call for longer than 10 mins before the phone shuts off and have to plug it back it into a charger just to get it to boot to the home screen
... hope there is a solution ... haven't read through this thread yet. just wanted to let you know you weren't the only one with the exact same problems

hahaaha well that didn't take long to read ... yeah my battery is somewhat swollen and i did drop the phone once ... time for a new battery i guess ... sucks

[x-posted from Cyanogenmod forums]
Ah well... gonna have to pull out a new battery and see if that helps in anyway. I will have a look at the device usage stats to see if anything is causing unnecessary drain. Since there has been a drastic change in the battery life after the upgrade, I do not want to blame the battery itself yet. Guess some app is driving the phone nuts.
Ok, I was just seeing the battery usage history in spare parts and I there are some interesting usage stats there.
Network usage - While Market, Android System, Google, Calendar are around 1% - .5%, almost 100% of the usage has come from Media. I think this has been trying to keep the network alive throughout the time. I dunno if network means Data or just the voice network. The packages listed under Media are Camera(twice), DRM, Download Manager, Media Storage. Is there any reported issues with Camera or Media Player?
Also, Spare Parts says my Battery Health is Good. Is this a reliable indicator of the battery life?

I believe spare parts receives the battery info via "Testing" which comes stock on android. Let me know how the new battery works out cuz I want to research further when it comes to phone environment versus the actual battery itself.

I have same problem with my battery. I guess maybe battery life since it already use 1 half year. Anyway, who knows.

new battery
just picked up a brand new battery today. gonna leave it charging overnight. will report later on whether it fixes the problem with the random shutdowns
... on a side note, i think there has been a battery issue since CM5 correct? in my sig there is a recalibration method by xda member 'my_former_self' for those who have not read it and if your battery is still good to go ... worth a try

new battery
so it turns out my battery issues was in fact the battery. the new battery is working awesome. phone hasn't randomly shutoff on me all day with heavy texting, some youtube vids, mild internet browsing, and several apps ... 17+ hours later about 2% charge remaining. gonna run the battery through its conditioning cycle.
fyi i turned airplane mode on when i was in class ... approximately 2 hours

New battery it is
After spending over 4-5 days with the battery, I pulled out the spare that I had (with a couple weeks of usage) and installed that on my phone. Just to be safe, I drained the battery after some initial charging and ran it through this battery recalib method.
I did this yesterday morning after it being charged fully. I also installed SetCPU after recalibrating. Its run 2 full days of regular usage and I still have over 50% charge left. Ain't that cool or what? I think I will leave it uncharged tonight also and I guess it should last the whole of tomorrow as well. I don't think even the stock cupcake or donut lasted this long on a single charge. So in that case CM 5.0.8 has actually managed to up the battery life a lot (with SetCPU and, sleep on end).

Exactly how long does your battery last? It's no secret that CM5 (and any Eclair ROM) is just plain poor on battery life in these devices, even on my in-warranty Magic it chews through the battery about 25% faster than any Donut ROM such as Dwang, SuperD or CM4.
Seido sell extended batteries which fit in the original phone housing (unlike those ridiculous ones on eBay which have an extended back and turn your phone into a 2001-era brick), they seem to get good reviews, maybe give one of them a go.

[Q] how to calibrate the battery for it to last longer??

i heard from my friend that HTC need to do battery calibration. is it true??

Don't think so. Another phone had a "calibration" routine but I haven't heard anything on this one. I tried the calibration routine from the other phone on mine and noticed no difference.

I really have a sucky battery life on htc sensation. I am trying to figure it out how I could get it to last for more than 12hours with average use...

I bought a replacement battery. http://www.amazon.com/gp/product/B0055QKZBS

While a lith-ion battery doesn't learn or have a memory, the battery does have a chip in it that needs to be calibrated. You'll need to cycle your battery from fully charged to fully discharged 3 to 5 times to calibrate this circuit. Normally a LI battery doesn't like to be fully discharged, so try to avoid doing this in everyday use. Better to give it maintenence charges. And heat is a big enemy of these batteries as well.
And seems to me 12 hours is pretty good battery life for a smart phone.

+1, very well put.
2 points.
1. There are also battery stats on the phone, which need to be built by full charge/discharge cycle.
2. Discharge phone till it's dead with no fear, battery controller shuts it down when there is some juice left. It's like reserve in your tank, it shows you have petrol for 0 miles/kilometers, but in reality there is another 5 litres sitting in the tank.

I worked in the cell phone industry for a long time. The best thing i have seen for a full charge is to regulaurly do a full charge and than turnphone off and plug back in until indicator shows full again(if it shows full already charge for half to full hour). I have always seen better results. Also if rooted wipe battery stats in advanced before flashing any radio or rom.

This may easily be true. I think I read that the battery doesn't actually like being fully charged and that most chargers shut down early because of this. Maybe your tip has something to do with that. I don't know myself how that will correllate w/ calibrating the charge circuit that I spoke of.
Google is definately your friend here.

That's a very intersting battery you got here. It has bigger capacity than the original one. Does it have the same size? Were you able to fit it in and put the original cover back? Have you noticed a noticeable improvement in battery life or is it just scam?
I don't have the tmo 4g, I have the european version, but I believe it should work too, shouldn't it?

Out of the box.... Use it till it dies completely. Charge it 100% without interruption.
I've ALWAYS had great battery life on all my devices using that method.
Do that a few times a month when it's convenient....you'll have a happy battery.
Battery and DRIVER need to be conditioned/calibrated.
I get 12-16 hours with fairly heavy use. If you want more, ya need to wait for different battery tech OR get a dumb phone.
Asking for more than 12 or so hours is just silly with a device this powerful and a display this large. I'm not someone who likes to cut the balls off my superphone to save a few hours on battery life. I'd rather get 12 hours and use this phone the way it was intended too, than get 24 hours and have silly progs like Juice Defender running. Unless you know you're gonna be lost in a forest for a few days, don't most people have access to a charger sometime during their day

Disabling the HTC Hub sync helped mine a lot.

My phone has been unplugged for 10 hours, I have 1h 17 minutes of display on time, taking 67% of battery. The rest is spread between Cell standby 11%, Wi-Fi 11%, Phone Idle 8% and Maps 3%.
It is now standing at 29% battery. I find that awful and can't believe any of you say it is normal. I have disabled HTC Hub and Sense sync and all the settings are pretty much the same as on my Galaxy S2.
On the SGS2 I manage to easily get 3 to 4 hours of screen time before the battery goes down to the thirties/twenties and a lot more heavy usage than I've managed on the Sensation. I'm on my second battery cycle and I really hope it improves because I'm very underwhelmed so far.

I found an even larger battery:

I might wanna give this one a shot, but I am a bit afraid putting battery not manufactured by htc in my phone.

Guys if bothered to look in the Accessories thread, you'd see that there is 1900 battery which some people already have and are very impressed with it.

Charging the battery
The battery is partially charged when shipped. Before you turn on and start using HTC Sensation, it is recommended that you charge the battery. Some batteries perform best after several full charge/discharge cycles.
I spoke to a HTC REP once regarding batt life on my DHD
He advised a calibration as follows for HTC phones
Make sure fastboot is off.
1. when your battery is low, do a full charge for about 8 hours, your light should now be green. once its full, disconnected the phone
2. Fully switch off the phone(pull battery out if needed then put in). and plug in charger again for an hour, the light will actually be orange even though it was green before you turned it off.
and your screen should load the charging icon for when its turned off.
3.once it is green, turn on the phone. (put in pins or passwords etc) leave the phone on for a minute, then fully turn off again.
4. charge again for an hour and your charging indicator should be green and your battery is calibrated.!

With all due respect....how is that awful?? It's fantastic....
I think you're too caught up in the percentage number the stats page shows for battery use. It doesn't matter one bit if that graffic shows the display at 99.99%. As long as you're getting a full day out of your Sensation....isn't that all that really matters? Or am I confused by what bothers you?? Sounds to me like you're getting a full day...unless you don't sleep??
You've been unplugged for 10 hours and it seems as if you have another 2-4 hours left with that 30%.... Whats wrong with that? It's great.
This is not a Nokia 6133 It's a dual-core superphone, with a 4.3" qHD display.
Of course by the nature of the tech, amoled will be more efficient with regards to display...but as far as I can tell, the GS2 doesn't last any longer than this phone on a regular day to day basis under normal to heavy use.
I get 12-16 hours on a charge with fairly heavy use. Sync, WiFi, Calls, Web, GPS...nothing disabled or throttled.
I wouldn't get caught up with that % number in the battery stats....it's misleading....big time.
Condition the battery properly....you'll never have any battery issues...unless it's faulty.
Also people just need to be realistic with regards to battery life.... A gallon of gasoline will get you much further in a VW Bug than a Bugatti....

There is an app to calibrate your battery, but you need to be rooted. Go to www.teamroyal.net and there is instructions that you MUST follow. Read up on it now so you can be prepared for when we get root. You also ONLY want to calibrate your battery once every 4-6 weeks, and only if it needs it. Doing it too often can fry your battery.
I know this doesn't directly answer your question, but I hope it will help many once we get root.

Original Battery life question

Hi, Getting close to 2 years on my gs4. The battery doesn't seem to hold the charge like before. How often do we need to replace the battery?

I don't think there is really a set time, its just that when it starts to go just replace it.

I'd usually do it within 18 months so you're on time for a replacement. Batteries don't last too long which is why buying a sealed battery phone is ridiculous imo.

Depends a lot on how you charged it over the years. Some people say it's better to charge those kind of batteries often and don't let them get below 20% or 50%. And If you use your phone while it' charging, that also decreases the life of the battery. High heat or cold also take some time off the battery's life.
Even if you do take good care of the battery, it will inevitably lose it's capacity over the years.

I feel the same way. But maybe nowadays ppl change phones pretty quickly, so by the time the battery's about to die, they're already getting a new one.

I have been using my phone for almost 2 years, and it already loses its charge so i decided to change it. I think it depends on your usage, if you use it for heavy use, it will loses its charge faster.

I bought new original battery after 12months of using old one,with daily usage i can get around 5hours of screen time

Well after 2 years, any good old battery will be singing on the last verse so to speak. Time to change it. Just normal!

My phone is about two years old now and I thought I needed a new battery. Instead I picked up a new samsung charger (the one that ships with the Note 4). I don't know if it's because of the increased voltage output but my phone seems to hold a charge better - and charge faster!

Hi, Getting close to 2 years on my gs4. The battery doesn't seem to hold the charge like before. How often do we need to replace the battery?

For me & my phone habits, it's usually after 15 months. On my N5, I put in a fresh battery after 18 months.

In general, the deeper you discharge the battery, the fewer times the battery will recharge. If you use your phone heavily, and always drain to 0% almost daily, that will result in a battery that will stop holding it's charge very quickly. However, if you don't use your phone heavily, or have access to a charger throughout the day to top up your battery long before it crosses 50%, then it will typically last a lot longer.
The fact that you notice a significant loss in battery performance, most likely means that the battery has either lost significant life, or at least significant enough to how you use your phone.

You may try the "Battery Calibration" app from google play store.
it's free but require root access.
This app remove the batterystats.bin system file. The OS generates a new clean batterystats file soon.
It's like you're refreshing your battery...
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated.
I use this app myself and it's great...
hope this help..

Read the last paragraph. Battery calibration apps don't do anything except generate a placebo effect and screw up your battery stats. To maximize battery life, you want to examine what processes are running and kill the ones you don't want to run, using Greenify or Autostarts.

I decided to replace battery after 15 month of intense use.

My S4 had the same problem. I reset the battery stats, and after that it works great now. Battery easily lasts for a full day.
Here's how you do it.
*Let the battery discharge while doing normal routine stuff, until it switches off.
*Turn it on again and use it some more till it switches off again. Repeat, until it wont turn on any longer.
* Remove the battery and hold the power key for 30 secs or so with battery removed(I do it for upto a minute)
* Install the battery and close it up and now connect the charger.
Let the battery charge to 100% WITHOUT turning the phone on.
*After 100% is reached, turn the device on and disconnect the cable and use it as you normally do.
DO NOT RECHARGE in between and let it discharge completely or till the point, it'll just be about to turn off, then connect the charger.

I've repeted this steps three times and it looked great!

I more than a year... 1 hour of screen

Calibrate your battery. . If you don't have the app .. charge til you get to 100% unplug charger then turn off phone, plug in charger while phone is off. . Charge until it's green. . Unplug and turn your phone on. . Repeat that process 1 more time and it will work

I just bought a new OEM battery from Samsung. What should i do first? Charge it with phone turned off to full then discharge it to 0 and then charge again to max? Do this one time or 3? maybe there is some article about what u should or shouldn't do when u get a brand new battery?

Hello sohail
My s4 has only average battery timing. Which is not enough for me. Plz suggest me some solution.
