[Q] Weird Battery Problem?? - HTC Sensation

This happened twice today..
For e.g: If my battery is showing 15% and then i restart my phone it suddenly shows 50% remaining..
Am using Battery Indicator to show me in % how much is remaining (though even the htc battery shows the difference in this case)
Any idea why is this happening and how to solve this??
Oh and how to stop the: Show Me app?? Keeps restarting and sucking my battery..

Could someone please help me out here with this weird problem??
It keeps happening everytime i restart my Sensation..

Try wiping your battery stats from CWM.Then charge battery fully>drain fully>then charge again it should be calibrated. oh and use startup cleaner in the market.

Its a 1 day old Sensation.. Havent rooted it yet..

I saw the same with my mine. I allowed the battery to drain until the phone shut off and recharged over night to 100%. I did that for a few cycles and mine seems fine now.

The battery % indicators only show what the phone software *thinks* it currently is.
The Sensation battery ranges from approx 4200mV (full) to 3000mV (empty).
The problem is sometimes the phone thinks those numbers are different. E.g. when you turn on your phone for the very first time, or flash a new ROM, if your battery was half full at 3700mV the phone would then think that was the 100% level (why they say charge a battery fully for a long time before turning your phone on for the first time).
This leads to various funnies such as a battery seemingly staying full for ages (the phone thinks 100% is much less than 4200mV so until you drop to the phones level your battery %age doesn't go down), and seemingly rapid drains where you end up with less than 10% left - but probably find in reality if you left it your battery would go on for ages at 0%.
Over time it learns, but best to wipe your stats after a long charge so it knows that 4200mV is 100%, and then don't charge your phone again until it physically runs out of juice so it knows what is 0%.
Another useful tip is to install the free BatteryLife widget from CurveFish from the market. That shows you the current voltage level as well as %age, so armed with the knowledge that full = approx 4200mV and empty = approx 3000mV you get an exact idea of how much you have left.

Mine does the same thing even draining/charging for few cycles

Yeah... I went to sleep with 100% charged and when i woke up it was yet 100% charged.. And when i check the battery stats it shows 0s but i was asleep for 8 hours.. Any way to solve this on an unrooted phone?

I had the same problem today too! Thought my battery was kicking ass...turns out it was 18% when I restarted my phone

What did you do about it?

Anyone know what to do about this to an unrooted phone??
Or is this a defective piece and i should get a replacement??

Mines has done the same but I haven't had the chance to calibrate it yet to know if that'll help. It has helped on previous phones. I don't think your device is defective though.

How do you calibrate an unrooted device??

I think it calibrates itself after a few charge/discharge cycles. Always charge it a lot longer than when the green light comes on (because if the phone thinks the 100% level is a lot lower than it should be, that green light may come on early), and for the first couple of charges let it dry out rather than topping up.
And install that BatteryLife widget from CurveFish, then you can look at the voltage. 4200mV = full, 3000mv = empty, regardless of what your battery %age says. Mine currently says 51% and 3753mV.

Having the same problem here, restarted my phone afew times now and the battery % keeps going up, then dropping rapidly! :s

Battery require bump charge?

Does your phone require a bump charge to actually get the battery to 100%?
Unfortunately mine does. I had an incredible and am familiar with this process. Unfortunately my Charge told me that I was at 100% when it was really closer to about 60%. I know I was at ~60% b/c I turned the phone off and plugged it in and the batter icon showed about that percentage full.
Not too happy about this. It would suck if I have to have the phone off to get almost half my battery full.
Any fixes? Is it possible its just a fluke since this is one of my first couple initial charges?
Thanks in advance.
I havent had any problems like this. It could be that you got a bad battery...

The android battery meter isn't a pure percentage meter, it also uses statistical history and current useage to guage how much you have left. So if you turn the screen on and pull down the notification area the screen and cpu just went to full use from nill, and the battery is probably a little hot, so with little statistics yet the battery thinks its being drained super fast.
Unplug it when it tells you to and don't plug it in till it asks to be plugged in, this will get you the most accurate battery readings. Otherwise don't worry about it unless its telling you to unplug it and then giving you the low battery dance before you get to your first destination of the day or something terribly bad.

[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.

HTC QUOTE
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.

for step 1 is it after 8 hours i disconnect the phone even though it will be green light earlier???

Going nuts!! Battery...

Have to charge almost twice a day... I believe it happened after latest 1.45.531.1 update....
Disabled all animation, got auto adjust for display, disabled all what I could.. Still gives me 12 -16 hours on standby only....NOT even using the phone!!!!
Does anyone have something like that??? Or there is some remedy I skipped?
Sorry if I repeat someone's question.
Running full stock, HTC battery.
Thanks in advance!!
Tester.
PS. Recently exchanged the phone.... First one R.I.P......died completely, didn't even charge.
Is there a chance they swapped a refurbished one on me??? How to find out???
can you provide a screenshot of the battery usage graph? also, have you tried getting an aftermarket, bigger battery such as the anker?
I was the same way as you. I checked my battery graph, and standby was using something like 80% of the battery with almost everything turned off. By the time I got home from work I would need to charge it immediately. I bought one of the Anker batteries on Amazon for $15 bucks or so, and I'm now getting about 2 days for a charge. I don't know what it was with my battery, because it sounds like my experience wasn't typical, but I didn't really feel like going through HTC when I could just pay the $15.
I'm with ya...
This phone was running PERFECT prior to the HTC update. Now I'm having a plethora amount of problems, including the battery. For example, prior to the update I would get 13-16 hours on HEAVY usage... Moderate usage? Try a day or day in a half. Now take today for example, I unplugged my phone a little before 7am and I had 20 something percent 4 hours later.
I'm telling you, that HTC update really messed this phone up IMO.
Thanks, guys!!
Will try to get Anker battery, I believe it's 1900 mAh.
But again something running on the background with that update. We'll see.
I'll try to get the graph, maybe someone'll get some sense of it...
Much appreciated,
Tester.
here are the battery stats...
Display..........74%
Cell standby...13%
Phone idle......11%
Voice calls......2%
THAT'S IT!!! Nothing else is running...... SUX...
Still gives 12 - 16 hours of life on almost idle......
I hate to say it,but if you're battery's dying a lot faster after an update,a bigger battery won't help much.
I'd be getting in touch with HTC and ask them what the heck is going on.
Really annoyed with the battery performance. I checked and only display is using 90% of battery. Tried everything to reduce it but no change.

I've had the same issue since the update. My battery drains at a ridiculous rate. I've become really frustrated with the phone since. I rooted it and flashed a custom ROM in hopes of solving the problem but it's the same deal.
I've confirmed it's not the battery either since I've got another one I've tried and only get the same results. Even with Juice Defender running I get nowhere as great a battery life as I did before the update
I'm doing decent 8hrs 20,mins on batt. With 40% left mostly text and internet browsing

Try clicking the graph at the top of the screen it will give you another screen that shows awake/screen time etc. Is your phone going to sleep when you screen turns off?
I was having the same problem and realized that some app was keeping my phone awake even though the screen was off. I uninstalled 80% of the crap I had installed and now my phone sleeps like it should and battery lasts amazingly long time.

How can you tell if your phone is going to sleep when you lock the screen? What is a good method for this? And if I find it its not sleeping when it should, is there a way to find the culprit easily?

Click on the graph in battery stats, it should show awake time and screen on. If your awake time is constant when the screen on time isn't, then chances are you've got an bad app somewhere preventing the phone from sleeping
my battery life was plain **** on 2.3.3., device was running hot all the time (=waste of energy), charging took ridiculous 4h+! When I took it off at the charger around 23:00 the battery was dead at 14:00 the next day with most time being idle!
Since my update to 2.3.4 things got so much better. charging takes around 2h and battery finally lasted a whole day and had 40% juice left in the evening.
Since I got my 2 Ankers+charger for 20$, battery life is crazy now. Been on one charge for 2d2h and still had 16% left. Pushmail on, wifi on (cellular data only when not at home), brigthness at 100%, taking video, pictues and some navigation, messaging and phonecalls. Oh yeah and a few minutes of flashlight use
I would say between slight and medium use.
If 2.3.4 worsened your batterylife, contact HTC or your vendor.
I now replaced the battery at 16% with the other Anker because I still need to do my 5 charge cycles on that one to calibrate it.
Here's an example of the graph. At the bottom you can see awake and screen on time. I pulled phone of charger last night, did some browsing, then ran for an hour with music playing in the background (you can see the small green bar on awake even when screen is off). After I surfed a little and left it off the charger when I went to bed. The phone is properly sleeping when the screen is off and almost 16 hours and still have 62%.
Before I uninstalled the apps, the awake time was solid green across the screen.
Anker battery worked wonders on my device. Before I would have to throw it on the charger after lunch as I like to go for a beer after work and the stock battery would never make it that far... Now when I get home from the bar I still have ~30% battery. Anker battery FTW!
flash a custom rom and u will go gaga over ur battery life. definitely works for me. on standby overnight drain 0-1%.
I found out that if you don't have strong signal at your location your battery drains pretty fast that's why I always connect my phone to WiFi at my apartment where my phone looses signal sometimes. now I lose just 1-2% of power during a night.
Sorry to hear about your battery troubles. A couple days ago I rooted and switched to "Android Revolution HD 3.0.4" and my battery life seems pretty solid. I wasn't having battery life issues prior to this though.
I'm currently in the process of calibrating the battery:
- drain it mostly
- turn off
- plug it in overnight while still off
- in the morning unplug, wait 15 minutes, replug for a few hours; do this ONLY ONCE or you may damage the battery
- power on, immediately go to recovery, advanced, reset battery stats
- start normally
- drain battery until it shuts down; a continuous stress test or stability test app is probably ideal
- once it shuts off, turn it on again to double-check that it's dead; it should only come on for a second or two
- while off, plug in and allow to fully charge; no fooling around with plugging/unplugging, just normal
- calibration complete!
I think you can follow a similar procedure (minus clearing battery stats) to refresh the battery calibration even without rooting/custom recovery. I've read the effectiveness is similar. The phone just needs to be retaught what "full" and "empty" mean, all in one charge cycle. If you calibrate it wrong you could have issues with it shutting off while still reading ~15% battery life.
Anyway, as I said, I'm in the process of doing this. Currently I'm in the "drain it" phase... with my screen at maximum brightness (remaining on), overclocked to 1.5 ghz, I've been running "StabilityTest" (from market) for one hour and fifteen minutes. It stresses both cores as well as the RAM. At this time, my battery is at around 30-40% or so, and it's getting really hot! The phone's temperature is reading as 54.8 degrees!
Also, yesterday I used the GPS for about 4 hours before it died, this was prior to any calibration attempt. I think this is within typical battery life considering that the screen stays on.
TL;DR: Maybe you just need to try a custom rom or recalibrate your battery. Miscalibrated battery can be caused by flashing/updating a rom, I imagine even when it's an OTA. Sense is crippling your phone anyway, you might as well give it a try IMHO.
get yourself an anker battery..I havent charged my phone since the day before and now i have 20% left! heavy usage

Battery Issue..Please help..

I am using the Sensation on stock ROM..and about two weeks ago got a minor update to it (which provided the power saver option on the quick settings menu)..And since about a week now, my phone takes an elongated time to charge..previously, it took only about 2 hours to fully charge the phone, but now it takes more than 3 hours..plus, it takes only about 1.5 hours to charge from 0% to 80%, but afterwards, it takes more than another 1.5 hours to charge the remaining 20%..but after about 90% it literally stops charging further, no matter how long I keep the phone plugged to the charger..But when I restart the phone at that time, it indicates the battery level as 100%..
Does anyone else has the similar kind of problem? And can anyone please suggest me what to do? Is it a problem with my battery or is it a software issue? Please help me..
Thanks in advance..

Perhaps you need to reset the "stats" of the battery ?
Charge the device to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings » About device » Status » Battery Level = Full.)
Boot to recovery mode and delete the battery stats
NOTE: To have the most accurate of battery stats, reboot the device immediately after wiping the battery stats and wait for CyanogenMod to boot completely to the desktop. Once your entire boot is done and you have full access to the device, go ahead and pull the charger and continue with this troubleshooter.
Do not charge the device until after draining the battery completely, resulting in it automatically shutting off.
Recharge the device completely and then use as you normally would.

I am also facing almost same issues with battery. The phone charges very fast from 0% to around 75%. The remaining 75% to 100% takes a long time. But it does reach 100%. It doesnt stop before. And if I reboot the phone when charge is 80% or 90% it will immediately show 100% on reboot. So which value was correct? Before or after reboot?
Another thing is during the day when I am using the phone and the battery is at any particluar level for ex. 45%. And I reboot the phone for any reason. After rebooting the battery level is shown as increased to 50% or any other value. How does battery increase on rebooting the phone?
My theory is that HTC Sensation is unable to read battery level accurately and therefore such incorrect values are reported. BTW this happens on both the stock battery and my current Anker 1900mAh battery.
Hey mate, did this error started to occur after you updated your phone or was it there prior to the update as well?
This situation was there before the update too. Maybe some experts here will give their opinion on this.

Shuts down when battery low, but not dead

I'm having issues with my phone shutting off when the battery meter is low but not dead.The indicator will be yellow and still shut off. When I power it back on and plug it in, its completely dead .
is the phone innacurately reporting the battery percentage?
Sounds like the battery isn't conditioned correctly. There are apps in the market to help with that.
Look in battery configs battstats prob in /data/system and prob elsewhere

Arent there other ways to condition the battery with an app? i heard like running the phone to empty and then fully charging? any advice?
The problem with running it empty is the battery will never fully discharge because the phone is reading the stats incorrectly.
can you recommend any specific app for this? do you have to be rooted?
You'd have to look at the requirements per app but I do believe you need root.
Your phone isn't going to report one thing, but "believe" a different thing because of bad battery stats. A Google employee has already debunked "conditioning" your battery by deleting battery stats; the phone uses it for reference only, not to make any decisions, especially when to shut down. Something is wrong with the battery itself, or your phone, not your stats.
Swyped, not typed, from my Digital Brick
It might be better over time. Had mine for two weeks now, and I had it run out on me three times. First time it shut down at about 13% left on the meter, second time around 8% and this last time at 2%. Good enough for me, but it's annoying if an untampered new phone doesn't report at least somewhat close to real battery-state.
I usually hook it on the charger at 15%-30% (approx 12-16 hours usage) in the evening, and sometimes have a few short charges (25-30 minutes) from the car-charger during the day.
I've never let mine get below 50% since I got it, but I just ran it into the ground with a terminal process ('yes && yes') and it went all the way to 0% and then powered off.
