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.

Hey guys I just got my Anker Battery 2 days ago and it says to let it charge and discharge about 5 times before getting better results. So far so good and its getting better. I'm on my 2nd charge but just so im clear on something here...
By charge to discharge does it mean to charge to 100% (turning the phone off) then discharge to 0% ( phone shuts off) and charge to 100% again 5 times? Been doing that and im not charging in between so it's a mess when it runs out while I'm not home (happened today!)
Also: any suggestions or opinions on the product so far?
Ps:was in supposed to clear the battery stats or something?

I only do it 3 times.
As soon as I get the battery I turn it on & run it into the ground. After it's shut off from a dead battery I plug it in & let it charge with the device still off. When the charging light turns green I turn the phone on & run it into the ground again. Rinse & repeat for 3 cycles.
I love my Anker battery. I get way better battery life with it versus stock & it doesn't overheat like it the stock one does. I use one, my buddy with another Sensation does as well, & my mom with her MyTouch 4G has one too. All are outstanding!
Sounds good...i should try it too
Sent from my HTC Sensation Z710e using XDA App
just ordered my anker yesterday - i think the 5 times advise is the same like deleting the battery stats - more a software then hardware related thing
Sounds like your training your phone to establish effective range. Personally I would run it into the ground five times, but some people say It's okay to charge when It's under 10%. Better safe than sorry is what i think. U only have two more cycles to go, suck it up.

I have had mine for a few weeks now and it is getting me at least an extra 20% with heavy usage...
Even the new Sensation XE only gets a 1750mAh battery I have read today...still under powered imo
The XE proves that the base Sensation we all have is definately underclocked and that running at 1.5GHz is quite safe...
Hello!
I've read many battery calibration threads. There are many methods and many ways to do it. So I am a little confused.
I am now on Stock battery with Revolution HD rom.
My Anker battery arrives on monday and I am preparing for it's use. To get the most juice out of it, I have to calibrate it.
My friend bought the ChiChitec 1950 and runed it down completely and then charged fully. In the Battery Monitor Widget it doesn't say that the battery capacity is more or less than the stock - shows 1530. Which means, the widget is showing wrong because the battery is different.
I do not want this problem.
I've read that you need to fully charge/discharge the new battery a few times first. So I have a few questions:
1) Which is it first: Charge or discharge? Puting the battery in, do I discharge till 0 or do I charge it to 100?
2) Is it better to charge it turned off or on - for the first time?
3) When to wipe battery stats: When at 100% or almost no charge?
4) Which calibration method for a new battery works for you?
I'll be greatly appreciate some help here. Thanks in advance. [:
The official response regarding battery calibration from HTC was:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour

Although that was during the EVO 4G days.
Here's the original thread http://forum.xda-developers.com/showthread.php?t=712990
So, I did everything as said in that post [ battery - amazing for now ].
Umm, the only problem is what I feared. The Battery Monitor Widget still says that it's 1580 not more. How to fix that, does anybdy know this?
I do know that u only wipe battery stats when it is at full charge
Sent From My Pocket
One thing I feel I should add to this thread that I've read elsewhere is that discharging the battery completely is not good for it.
I got the two chichitec batteries with the wall charger about a month ago. I've labelled these #1 and #2. After a few discharges I noticed #2 drained a lot faster. I thought something was wrong with my phone, but #1 holds its charge much longer and better.
My only reasoning is that it's been discharged less. But this could be a coincidence and just a bad battery for all I know.
There is a setting to manually overwrite the mAh on battery monitor pro widget.

That mah reading is default for sensation
Yes, found the manual override. Much better.
Well. I think my Anker today drained a little bit too fast, so I will not dishcarge it completely again. Will test for a while.
Battery Life on the new CM7 #5 Stock kernel
Seems about average
i have a htc sensation xe with beats audio
phone is rooted and flashed with OrDroid 4.0 Ics 4.0 Sense... before i also tried ARHD... bricked kernel...
Stock battery
i have this very weird problem..
my phone has inaccurate reading of the battery..
here are the issues:
1. the phone drains the battery by 2% each interval instead of 1%.. I mean its like, 100%,98%,96%,95%,94%,92%,90%
2. the phone lasts longer on the terminal part of the battery.. its like its the longest 3% of the phone's battery life!
3. whenever the phone is drained, and if i insert a charger, it will have inaccurate battery level reading.. here is an example:
my phone is at 9% of its battery life... i plug the charger to the phone.. it will charge.. after charging for around 2 hours it will show that the battery is at 57%... i plug the charger out.. restart the phone and bam! the battery will be at 100% or 99%.. i mean, its annoying.. i have to restart the phone everyday so that i can get an accurate reading of the phone's battery..
anyway...
i am done recalibrating the phone.. ive done this 3 times now...
and i also did every method for recalibrating the phone..
ive also done this one: http://forum.xda-developers.com/showthread.php?t=1558140&page=5
the smali editting thingy..
and ive also done placing a small business card on the battery to push the battery closer to the pins..
the only one i havent tried is to buy a new battery which is expensive! i dont believe the problem is in the battery though.. i think its in the firmware or something... i dont know.. anyway.. can anyone help me on this one??

From what I can understand you don't have any problem at all. The same think happens to me. Whenever I reboot the phone it will show at first more charge than it has, but after a few minutes it will go to where it was. Don't worry about percentage drops or increments, if your battery lasts as it should. I myself thought that battery calibration way essential after flashing, etc, etc. But now I am convinces that it has nothing to do with battery life.
Just IGNORE the percentage and enjoy your phone

hey can u update me if replacing the phone's battery solved the issue?? if it solved it then i guess i'd buy mine a new one too..
Hi there, as above poster said I'm not sure this is really a problem. Mine also does this say I'm on 95% then when I reboot it will say 100% for a bit then go back to 95% the true percentage. So what I'm saying is sometimes after reboot an inaccurate percentage will show for a time then it will catch up and show the correct percentage. It will happen with a new battery as well this is just how our device works. I recently purchased a new mugen 3500mah battery and after reboot I still get the same issue. It's not really a problem it's just the device catching up with the accurate battery percentage. As for the two percent increments, my device does not do that.. not sure why it's draining at 2% increments unless this is just how much your device drains for a specific amount of time. Perhaps your battery is draining At 2% increments because this is your consumption.? I really wouldn't worry too much unless it's jumping increments without being rebooted, like going from 73% to 60% to 50% all in a matter of five minutes. If that's the case then I would become concerned and likely think it's time to purchase a new battery. But you are only draining at 2% increments and I really don't think it's cause for alarm. Do watch it closely and if the percentages start to jump and drain at bigger increments, then perhaps invest in a new battery. But for now I agree with above poster and really wouldn't be too concerned. As I said just keep an eye on it and if it gets worse as the example I said, then get yourself a new battery. Until then I think your ok for now. I hope this helps. I wish you the best!

Have ever tried letting your battery drain 100%. until the device shut's down. and then take the battery out for oh let's say 5 second's. And then put the battery back in hit the power button . If it powers on your battery isn't fully discharged .and if it is plug it in and let it charge to 100% just my two cent's but worth a try

So i got the anker a few hours ago and the bug presists. i made full charge and calibrated the battery. it is still mostly discharging 2 % at a time and the phone stay a very long time on 100%.
Hi. I'm using htc sensation xe with viperS 1.4.1 rom. normally it took 2.5 hours to charge from 10-20% to 100%. but lately, (for about a month) it takes up to 4 or 5 hours to completely charge it. I bought a new battery and charger, but i can't feel any difference. i have some battery drain problems too, but it seems almost everyone has that! is there anything i can try? thanks.
For the battery drain problems you can get Better Battery Stats. This app will let you know if you are getting any Wake locks. Wake locks can be the biggest battery drain. If you are getting wake locks that app will help identify which app is causing the issue and you can delete it! You can get better battery stats here on xda, or even in the market. This will help your battery drain issue. About the charger, my charger takes around 4 to 5 hours to charge fully also. Never thought it was a issue.... I'm thinking it's normal, however I could be wrong. Best wishes.
