[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.

Chichitec battery

Just got it in the mail today. Fully charged it and ever since I took it off the charger, (4 hours ago) It's still at 100% battery. Plugged it in and still gives me a green lit LED, indicating full battery. Best buy for the phone for only $20!

I got mine today.... Thats good news for me.

i just got mine also but um curious my charger has purple and blue lights.. my charger just went from purple to blue.. does that mean its full? because i dont think i will have a green light....

Yeah the op was referring to the phones led, the wall charger turns solo blue when finished.

It's usually not good to overcharge a battery, but I doubt anything will happen.

Chichitech Battery stats first use
So after first charge, got around 15hour of use on one charge. Sorry about the pictures being blurry.
Voice use was about 3hr 4mins
Display was 1hr 11mins
Standby and cell use was 15hr 34mins or so. http://media.xda-developers.com/images/smilies/biggrin.gif
Original HTC battery lasted about the same if I didn't use the phone alot, meaning i used like 1-2 hours of voice and 1-2 hour of display. Chichitech battery would last atleast 24 hrs on idle... http://media.xda-developers.com/images/smilies/eek.gif
Recommend the battery for now, not sure if it will hold up after frequent recharges.
Battery recharged in about 2hr 50mins from 0-1% to 100%., double the time if using external charger that came with the battery since its only a 400ma charger. http://media.xda-developers.com/images/smilies/confused.gif
HTC battery recharged anywhere from 3 to 4 hours on A/C power.

[NS4G] Why won't my phone properly charge?

I am having horrible issues with my Nexus S 4G. The phone does not seem to charge properly.
What is wrong with this phone? My Evo would charge at around 800+mA in, while the NS4G barely gets above 100 with the screen on and around 400 screen off. Is this just a Samsung vs HTC design issue or should I return this while I can?
Additionally, the charge never gets to 100%. I've read that charging while the phone is off alleviates the problem but it hadn't helped at all innumerable case.
Is SBC available for this phone? I really enjoyed that extra feature on my old phone.
Thank you!

Mine doesn't charge to 100% either. It actually seems to charge to around 80% because as soon as I unplug it, it drops to around 80% within the first hour and then discharges normally from there.

The battery is not supposed to charge to 100. Its a feature that turns charging off right around 94 percent to preserve the life span of the battery it self.

you can try wiping the battery stats from the recovery. some times it helps.

Sensation takes 6 hours to charge from 1% to 100%

Hi all,
ever since i rooted my phone and flashed another ROM, i have been having this problem of very very long charging to 100%. I did attempt to calibrate the battery after flashing the ROM by the way.
First CM7, then Virtuous Inquisition, now Ordroid.
From 1% to 70% it would be quicker. Then from 71% and onward, it will take hours to move. I am using the original usb cable n adapter for charging, i can't seem to figure out what can be wrong.
Or did i calibrate the battery in a wrong way?

You charging via a power socket or a USB port in a device like a computer or something?

I think he was implying he's using the usb with wall charger
Mine takes almost 3 hours, more if i'm using it a lot while charging -- all stock with ICS

Hi, I'm on ordroid too and it takes me two to three hours to fully charge with my wall charger. I'm using a different battery, extended life Anker battery. My stock battery was so bad it took too long to charge and ran out so quickly! Are you using stock battery still or a another battery? If it's stock, you might want to consider a long lasting battery. I've found it charges faster and lasts longer. I hope this helps

It is intended to do that, i think.... I read before somewhere, too lazy to look for it though lol... It slows down the charging when its near completion to avoid battery damage.... Mine does the same thing, i give my phone atleast 7 or 8 hours from as low as 15 to 10 percent

Hi,
this not normal. My Sensation takes between 1 or 2 hours to full charge from empty.
After charging, how long you can run on battery?
When charging, is screen on or off? any application draining battery?
Regards

I think you just might have an issue with your charger. Go get a new one and see how that works out for you. If that doesnt fix it - get an anker battery

Honestly this seems more likely to be not normal. 0 to 100 in one hour with this phone would blow me away.

Are you serious..? I always thought something is wrong with my phone because of the long charging time. Many in the forum of custom ROM will feedback they charge for 2-3 hrs to full battery though..

My battery can last for 4-5 hours under constant usage of data and apps, before going to less than 10%.

Try to use different usb cord and wall charger, if it still giving you problem, i suggest u either do a fresh install your current rom or install a different rom.

try a different wall charger if the problem is the same then u need to consider a other battery

thanks for the advices..
it just came to my mind, that before I flashed any ROMs, when i was still using stock HTC Sense 3.0, it used to only take 2-3 hrs to full charge. Now it's 6.

Doubt that, mine charges to 100 in about an hour and a half (Running HyperNonSense).
If you're using a USB charger, make sure the phone knows the power source is (AC) and not USB. USB will charge a lot slower. Dial *#*#4636#*#* for testing info and look under battery information (There's probably another spot in settings but this is my favorite).
Also use the original power adpater that came with the device, or one that came with another similar device.

Mine takes 4-8 hours to charge in any ROM. Last night it was almost 9 hours from 3% to 100%
When it reaches 60 more or less it's like 100% if you reboot. I do reboot everytime to stop the wait. I don't know if that's bad but this phone charges very slow after some percentage is reached.

My phone take 1hr.45mins

This is crap, what you´re doing!
If you charge the battery, the phone doesn´t know how much capacity it got. (Could be an old battery or a bigger/smaller non-stock battery) So the device will recorgnice how fast the battery adopt the power and estimate when it slows down on a specific value when to stop and show 100%.
If you will restart the device during the loading sequence, it makes a battery calibration and thinks your on 100%. But of course it is still on 60%.
Your just fooling yourself

[Q] Battery about to die?

Hi all,
I got a question about my battery.
I always check with currentwidget to see when the battery is at 0ma so it's fully charged.
Although my sensation XE doesn't ever reach the 0ma after a whole night of charging.
It stays arount the 9ma and then jumps to 12ma etc.
My old desire HD always went to 0ma after whole night of charging.
Is this normal or can I say that the battery isn't as good as it belongs to be when it's new?

Hi,
You should not compare the Sensation with the Desire.
The battery on the Sensation is really [email protected]
How long do you get from a full charge?
Do you get reboots?
Do you give it a few cycles (charge/discharge) before making your decision ?
Have you tried different kernels?
Do you use Better Battery Stats app?
These are the questions that seem to matter on the Sensation battery.

Thanks, well i tried different kernels. And now iam running faux latest beta.
I think that one is best for me. I have sometimes some fast reboots. But just posted a last_ksmg log
to check what is causing it.
I give it a phew cycles and normally i get around 16hours of the battery, not so much.
When i unplug it too start using it sometimes drains kinda hard.
I don't use any battery apps on my mobile, also not the auto battery calibration script.
I was thinking about getting an Anker battery for my mobile. But just wanted to know
if it's normal it never reaches that 0ma.
Thanks for your message!
