[HOW TO] Calibrate Desire Battery

Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.
Mod Edit: There have been a few reports of damaged batteries by people on this thread. There is a chance that this MAY damage your battery. Please bear this in mind if you choose to follow the instructions above.

supportyou and the app!

Thanks for that. At what point do you wipe battery stats? After the process is complete?

Also wondering about this

You should wipe battery stats after its fully green (when powered off) then boot the phone back up.
You only need to do this once
I.e.
Charge till full when powered on
power off
charge till full again
boot into recovery wipe stats
boot and continue to use as normal

It works!!!
That's fantastic!
I read this topic this morning and tried immediately. Since this morning i only lost 4% until now. That's great news!
Thx a lot, man!

first post

takes a long time to charge my Desire, but then i'll test this one!
Hope this will make battery life better. I have the same problem as described in first post (drops immediatly from 99% down to 93% )

Can someone suggest me how should I go about doing this if I use multiple batteries?
I'd imagine the phone can only be calibrated to 1 battery. But if I were to use another battery, would I screw up the calibration to the original batteries?
Right now as it is with moderate usage I need 3 batteries to last me through the day. :S

3 batteries?!
What rom are you using and how exactly are you using your phone?
I have just one battery and it lasts about 2 days with moderate use.

I am using this ROM: (sorry can't post link)
[ROM] Rooted Official HTC Android 2.2 (FroYo) ROM [Market issue fixed]
With my typical usage, I unplugged the phone in the morning from the charger, by the time I knock off from work, I would have left about may be 20%. With stock ROM and a single battery, there is no way that I could last 2 days with one single charge. My main use is web browsing, RSS, Facebook and IM. My estimation of my solid screen time is about 2-3 hours.
So I bought more battery just in case, and played with custom ROMs. I ended up using up a whole battery in 4 hours or so. Definitely something is wrong here. My gut feel is that both the ROM and batteries are suspects. Being a newbie I really need enlightenment.

Is it really needed to wipe the stats? I think I've accidently done this once already... cause the battery life is much better.

since this procedure, my battery stays at 100% since nearly 2 and a half hours now and i did 2 text messeges in between and recently checked the bat about 4 times
this couldnt be possible..
i mean the battery is almost doubled in comparison to how long it lasts before
is this possible??

yes it is possible

but how?
i mean in this time the battery would have been dropped to arround 97
and now its still full?
i mean these are stats how are they increasing battery life? the batterylife is given from the cell itself?

One X battery fix?

Okay so I presume all of you one X power users have noticed a the horrible battery performance. I only got my one x yesterday and I'm already frustrated with the fact that i yet again have to carry my charger around with me. Is there a fix? I have root and custom recovery. So if there is a fix for this please someone let me know.m

Since I flashed the Revolution HD I got excellent battery performance. Without doing too much stuff (just calling and texting), battery remains > 50% at the end of the day. I would really recommend that rom.

I've just flashed it, going to see how it goes. But I would've expected HTC to bang a beast of a battery for the beast of a processor and massive screen its gotta run. Oh well, still early days, hopefully we'll see massive software improvements.

Not really, no. Personally I did not unlock device, neither root it, neither installed any fix. And I must say that I'm more happy with battery life than I was with my previous phone SGS2. More then 16 hours here with 4 accounts synchronization on, 3g/wifi on, and sometimes gps + music on (for Endomondo). I'm really happy with my One X.

ARHD Rom, auto-brightness, plain wallpaper, no haptic feedback, no roaming, managing syncing, and a few other tweaks will leave this devices battery life as one of the best.

Yep. Relax. I got 6 hours from first charge, 10 hours from second charge, 12 hours from third charge...
After over two weeks I'm now getting between 18 and 24 hours. Give it a couple of weeks before judging battery life.

I try to use as much as I can the first few days, and time it so that you have about 10-30% charge left when you reach home from work/school and then I let it charge overnight.

I know quite a lot of time was spent idle, but 60% after 7 and a half hours isn't too bad http://twitter.com/Dev_Meltus/status/194082996767309825/photo/1/large
I've not really had a problem with battery life so far.

how did u use it on those 7 hours? idling?

Have been seriously contemplating getting the One X.
My first choice had been the Galaxy S3..... but the One X seems the better choice.... I have had the iPhone 4 for almost 2 years, so now it's almost upgrade time If the Galaxy S3 had no physical home button I would be taking it.
Had been worried about the battery life of the one x but after reading these and a few others it seems worth it and it's available in black (dark grey but darker than S3 metallic blue)
I Just hope I don't have issues with app incompatibility for the apps I use on iPhone.

With normal usgae, I've got more than 10 hours after one charge. Not so happy with it but it's good enough for me.

have you got yourself the One X? if so, how is it compared with your previous phone?
i also want to swap my iphone 4 with One X and looking for different experiences especially with the battery life

I've turned everything off and left my phone on idle, my battery issue has persisted for over 6 months now (I bought it in Singapore on release day). With screen on min brightness, static wallpaper, most apps off, my battery drains fully within 6 hours. If I actually do anything with it like make phonecalls, it drains in hours. The battery phone is constantly hot, when on charge It's almost too hot to hold. If while on charge (AC) I use it to make a call, it complains that it's not receiving enough power. Should I look to get a replacement from HTC? I'm still using stock rom so it should be covered under warranty?

Sounds like the htc amaze battery overheat..
Also get gsam battery app.. it will tell you what apps are using what % of battery.
I also use advanced task manager from play store.. it proved to me how much gmaps Facebook and other bloat was ALWAYS RUNNING!.. I got root and froze it all with big improvements
Some of us who htc amaze w no warranty bought a new battery and that fixed it

Aside from your time travel/exaggeration, I suggest better battery stats, finding out what is causing wake lock, and killing.it.
Your phone is fine, but you have some crapware on it.

Battery jumps

Hi guys!
I have question.
When i have charged my HOX, and just normally use it, it looks like it jumps from 100 to 99, to 98, to 92!! It just stick to 98 for a while, and after that it jumps to 92 (just an example). I am on leedroid's ROM atm. Is this a common problem?
Thanks!

I'm on stock ROM and using battery widget monitor and I get the same think, guess it's just they way the system reports the battery percent. Had the same issue on my Sensation ad well.

Hmm, i think a software tweak can sort this out. Saw there is a tweak for sensation too right?

When you charge your phone it will charge to 100%, then take itself off the power source. It will then deplete the battery to 90-95% and then go back on the power source until 100%, and repeat. This is why you have those jumps in battery percentage. Once it charges to 100% once, it will be "fully charged" even if it is in one of those discharging states.

[Q] HTC One X battery life issues, first charge problem or.....?

Hey guys, I just got my HTC One X a few days ago and this is my third day running on this phone.
I wonder if giving it a first charge for 8 hours was needed to condition the battery and giving it as much battery life as possible.. Because when I first received the set, the set was without juice. So I charged it up till about 15% and I received a notification about an FOTA update and I went ahead with it.
After the phone reached slightly over 35%, I let the phone install the FOTA(while still at it's first charge) and it hanged halfway.
I didn't know what was happening so I tried rebooting the device(as removing the battery wasn't possible with the One X). After several tries of holding down the power buttons, I removed the microUSB cable attached to my phone and the phone went blank and it restarted by itself.. Take note that the battery was only at ~30% at that point of time..
And one thing I noticed when the phone didn't respond during the FOTA update was that the AC plug was not as hot as it was used to when charging.. Yeap, so does anyone know if I have actually 'damaged' the battery or maybe it's just the handset that's power hungry? Thanks!
PS, Thank you for taking your time to read this long wall of text and taking your time to reply to my query!

I'm not too sure what the problem is now. Is it about the power draw, or did you brick your phone and wondering if it was caused by a damage battery on your side?

Well, I'm just wondering if me not giving a proper 'first charge' has anything to do with it's poor battery life or it's just natural for the device to be this power hungry, haha.

How much screen on time ate you getting?

You shouldn't charge while flashing the OTA.
I don't think you did any harm.

Assuming your FOTA Succeed,
Try...
1. disable fast-boot (Settings > Power > Untick fastboot)
2. Power Off
3. Charge (until green / 100%)
4. Power On
5. enable back fast-boot
6. Hopefully you got real battery-stats already

I've noticed some improvement of the battery life of my phone after flashing it with a custom rom.
With a giant screen, a powerful processor, and an elegant packaging, pour battery life is kind of expected, for me I've put chargers almost in every corner of my home, at work, and in my car.

I normally get about 3.5 hours ++ screen time on a full charge, auto brightness.

I am getting 5 hours of on screen time on my stock Rom. Is that possible to get more screen time like 9 hours on custom Rom ?

I didnt charge it when I first got it either. I booted it instantly and used it untill the battery was completety drained and the phone shut down untill I recharged it completely and my battery life is horrible. The worst of any HTC one x so I wonder if I might have damaged the phone aswel??

Charging it when you first get it does nothing. If you have such bad battery life it is probably a faulty phone.

My battery was ok on 1.26 then updated to 1.28 and it went beyond awful but after about a week of use on 1.28 my battery has improved a lot... Bought an external charger while was waiting on next update but before I received the charger battery went boss !! So my guess is give it a few days and don't be inpatient with it as it will come around

I'm having issues with my battery life. I'm also new to the Android platform -- well sort of, I've used CM9 on my HP Touchpad for a while now, but this is my first Android handset. I've had the phone for almost a week now, and I've noticed that I barely get around 9 hours of moderate use per charge. On average my on screen time is about 3.5 to 4 hours. That is terrible. My iPhone 4 is lasting twice as long as my HOX and I've had that thing for about 2 years now. Any tips on improving battery life?

2h30 min to fully charge the one x !?

So, is this normal to wait 2h30min and maybe more (!) to fully charge the phone ?
new phone, original charger and original usb cable...

From about 15% mine takes 3 hours

How the hell are you draining in 8hrs - constant use?
Normal days without gaming gets me 17+ hrs
Even streaming all day via data connection gets me more than 8 hours.
I noticed when I got mine, I thought it had low battery as I was always using it, due to the 'ive got a New phone, can't leave it alone bug'
Normal usage, few calls, bit of browsing, bit of gameplay etc should get you through your working day quite easily.

i can easily get through a day without wondering where i can plug in my baby.

i get over a days use with my battery since the last software update... but charging time does seem fast.
is there such a thing as overcharging in terms of degrading battery life?

Please use one of the existing threads on battery life and charging time.
We already have plenty of them and would like to keep everything compact.
