[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:
http://uk-batteries-galore.co.uk/HTC/32640-Sensation.html
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.

[Q] Draining battery on first use?

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).
Click to expand...
Click to collapse
(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

Battery And Charging problem

hello,
I started charging my tab, it got charged till 99% and then i kept on charging it but it didnt went above 99% so i thought may be its because i am using the cell. So i switched it off and kept on charging , The battry icon was charging towards the end part (like the last 10% is getting charged) but in brownish yellow collor (sort of dark orange color) i kept it for charging in this way for like an hour.. Still when i turned on the tab, its 99%. Why so??
I havent rooted it yet! its total stock..
Bought it just 5 days ago..

About half the time, my tab will only go to 99%. Since it's only1% I've never given much thought to it, but I do experience the same problem from time to time.

I'm using a p3113. I've never noticed much difference in how long it lasts. Most days, my tablet will last all day whether it charges to 99% or 100%. You really shouldn't see any difference to speak of between a 100% charge and a 99% charge. I personally think it's an overcharge feature to keep it from overcharging. I've actually seen it jump from 100% to 99% one time. If that's the case, then it's a good thing. You could try to bump charge it like I've done to cellphones that won't fully charge. I really wouldn't recommend it since 1% is practically nothing.
Charge it up (powered on) until it's finished.
Unplug it, and turn it off
Plug it back in to charge (still powered off) again, until it says it's finished.It will continue to charge now.
Now unplug it and turn it back on.
Plug the charger back in (powered on) and charge until it says it's finished.
Keep doing this until when you have it powered on, it should say 100%.

The battery charging end is defined with two parmeters: the battery voltage reach a voltage close to 4.2 V and the battery charging current gets under 200mA ( a value I have estimated on my 5110 model) .
If for some reasons the residual current do not get under this limit value ( # 200mA) while the maximum battery voltage is reached , the state of charge stay screened at 99% !!!!!
The 4.2V battery voltage is a safety limit that a Li-Ion battery should not exceed. Most often the battery voltage is stabilized close to this value at the last stage of the charging cycle and the internal charging progam decide that the charging cycle is finished when the battery current gets under a predifined value.
I have given some examples of charging cycles of different smartphones in my blog : http://78michel.unblog.fr (sorry most examples are in french).

So I should stop charging when its 99%?
How many hours does ur tab lasts after charging 99% ?? Cuz mine doesnt lasts even 4 hours .. never charged 99% (just bought it somedays ago) did it yest , its working well now .
Screen takes too much battery ,.. ny way arround it to have better batery life? i saw CM10.1 but it has probs with gsm device so I m not using it ..

I think it is better for the battery life to stop charging if the state of charge level stay on 99%, because the charging current is maintained continuously in the battery and I think this is not so good for the battery life.
You can check the battery current in the battery with diffrents battery monitoring systems. I use Battery Monitor Widget. This is very convenient app. to analyse the charging cycle and the draining of the battery.
Analysis of my 5110 here: http://78michel.unblog.fr/samsung-galaxy-tab-2-10-1-tests/
The screen of these tablets is the most current draining component. At max screen brigthness the battery life is a less than 6 hours on my 5110. The brightness should be setted as low as possible to improve battery life, other componenet such as WiFi... GPS have very low impact on the battery life.....

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!

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.

galaxy j7 battery problem

i think my phone has some serious problems and i'm wondering if it's the battery dying or a short circuit
when i plug it on a charger while of it shows a normal charging image but how it switches from one animation to the other so i can see the status of battery percent it's like a short on the screen happened
it chargers to 100 but when i switch it on it shows mybe 95 but never 100 and if i connect it to a charger to get to 100 it only decreases
it gets warm now days which did not happen and it like drains 50% overnight which is obviously not normal. these two days the battery life is like 4 hours with internet wich with j7's battery it should not happen. if i switch it off and then on again i loose like 20% of battery and if that is all i had i get 0% and the phone doesnt switch on. the phone never had contact with water . it's been 4 days since this started and it happened all of sudden like today my phone stays up to two days at most and i just woke up it barely finishes a day without data and with power saving mode
i'm sure it's not about background apps or any activities because i hard reset it already and i don't have any app. and it's not about wifi or sync or poor network i tried all that. i did everything it didnt help. i could buy a new battery but i'm scared it might be a short because i don't think a battery can just die in one night like this.
can anyone help me with this or it's nothing serious and i have to change the battery

it gets warm now days which did not happen and it like drains 50% which is obviously not normal. these two days the battery life is like 4 hours with internet wich with j7's battery it should not happen. if i switch it off and then on again i loose like 20% of battery and if that is all i had i get 0% and the phone doesnt switch on. the phone never had contact with water . it's been 4 days since this started and it happened all of sudden like today my phone stays up to two days at most and i just woke up it barely finishes a day without data and with power saving mode
i'm sure it's not about background apps or any activities because i hard reset it already and i don't have any app. and it's not about wifi or sync or poor network i tried all that. i did everything it didnt help. i could buy a new battery but i'm scared it might be a short because i don't think a battery can just die in one night like this.
can anyone help me with this or it's nothing serious and i have to change the battery
