This really works - doubled my Desire battery life!!!

HTC recommended solution!
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. Your battery life should almost
double, we have tested this on our devices and other agents
have seen a major difference as well
I was very reluctant but after trying it I must admit it does work!
Good Luck!

In my opinion the battery recalibration doesnt work..
I mean, after that, the battery show 100% for a very long period (this good), and goes to 90% jsut after a long period (this good again).
But after that, it starting going down faster than the normal behaviour OR sometimes the phone power off its self when the battery is still more than 10% instead to power off when the battery is at 5 % as usual.
That what i've noticed.

That is calibarting your battery need to do when you get the phone initially. you cant do that every time. Honestly if you do that your battery will be Sc***ed

Ohhh *****y!

Not being *****y, the OP posted something that's already on here so of course they're going to get flamed...my response was to the guy calling me a prick (and it would seem they think there's a swear filter on here, that or they're just so cool they use numbers instead of letters)

Some nerds spend too much time on forums

Not a nerd mate, just have an interest - work gets boring time to time and when I'm not DJing I need something to take my mind off things...if you're going to try and talk a good game you'd best be able to back it up
As a quick note, this method doesn't work per se but it gives the impression of longer battery life - it stays at a high % for longer but then drops off quite quickly

... after all that....
right then people. lets be constructive and help a chappy out. I've recently had absolutely sucky battery life. It was OK with LeeDroid 2.2e, latest radio, but then I upgraded to 2.2f and everything went to pot. Seriously, just with moderate use I was getting 12 hours at best. Overnight charge, unplug at 7am, by mid afternoon it was switching off again. This is not how it used to be.
So I switched to Oxygen 0.1.3 Beta - still sucked
Now on CyanogenMod - which I love, but battery life still sucks. Trying various radios, but IT ALL STILL SUCKS!!!
I've now switched over to 2G only, turned off auto sync and mobile internet, except when I want them, just to get through the day.
Help!
I have searched and there are generic answers, all of which I have done. I have recalibrated (don't start that flame war again please) and found negligable benefit.
Your thoughts would be much appreciated (short of buy a bigger battery).

Have you tried a stock ROM at all? It could very well be something in the custom ROM(s) you're using. At least then you'd know if it's the handset itself

Hmmm... interesting thought. I may well get a full on Orange UK RUU on the phone and see what happens. I'll report back if and when I get round to it and test it out properly.

There's your issue - there isn't an Orange RUU
You could try a stock WWE one, though (with a gold card)

That should work, for the sake of trying an RUU I'd just go with a stock one but thats your call

Battery Problem

Ok, take a loot at this screeny. I think my battery is either super decalibrated, or just bad. I've already let it run until the phone turned off, but I don't want to keep doing that as it's bad for the battery. (Super-saturation is not good for li-ion batteries) Any recommendations?
Edit: How about I actually attach the screenshot?

It's done this for every rom. I'm on virtuous sense 2.0. I clean wipe before every rom, so I don't have the slightest idea what's going on here. Although last night I did test charging my extended battery and it would charge, then drain while still plugged in. I am mega confused.

had the same problem on my stock Dz a few months ago, battery would fluctuate like crazy (would drop to line 15-20% suddenly and then go back to 60% when phone was restarted) wiping battery stats would not fix it. Turned out to be a dud battery htc replaced it and all is fine.
If you want a more technical explanation every battery has a sensor in it which reports voltages to the phone which the phone then interprets as percentage battery left corresponding to the values stored in the battery stats file. Our battery sensor is malfunctioning and reporting weird values to the phone which the phone is showing as fluctuating battery level.
Hope that helps.

[Q] Very strange battery behavior.

Hi all... first post, first problem with android... and hopefully a long time here in xda!
So I have the T320 (8.4 pro) and I have a strange problem with my battery. Is not only that it lasts no more than 4 hours (screen), the problem come by low and high battery %.

By low, the table shuts down and after starting it again, it shows between 5 and 10% battery!!
Something similar happens by charging... it shows 90% and no change... and after a reboot it shows 100%.
Is my battery dying? Should I wipe and restart from zero? Cyanogen?
The speed how fast battery drains is also extreme compared to stand-by times... but I assume this is more or less a problem of this tablet.
Many thanks in advance!

Having similar issues. Found mine dead out of nowhere one day. Never had custom ROM on it. Did factory reset now it seems like it doesn't want to charge .... Charges VERY slowly if at all.
Sent from my SM-G900T using XDA Free mobile app

i have the same issue, dropped from 50 to 15 all of a sudden , will try calibration , anyone else noticed this ?i picked up mine used so unsure whats the issue

i found better battery life after i did a factory reset. i bought it new and set it up and since then had 1 Sammy update but last week i reset it and it clearly made a difference on my 10.1. yesterday i had 2 hours screen time and on battery for 2 day and some hours and had 60% left.

Add mine to the list....seems to be doing the same thing here. Haven't been able to sort it out yet.

Took the back off mine tonight and reseated the battery connector. Then charged like below. First to time in a while it charged up like this.

can you post a pic of videos of how to pry it open ? hopefully simple with a prying tool

I just very carefully went around it with one of those guitar like plastic openers i have laying around from the many tablet/phone repair kits i have used. I probably rebooted it 5 times before i finally popped it apart... thing just did not want to charge. This was the first time i saw it ramp up 1% at a time in a while. The other thing i noticed it was doing was jumping from ~70% to 100% instantly.... The graph showed it too. I didn't believe that was really happening.

some pics would help , is it between the screen and the metallic part or the back and the metallic part ?

Opened mine up because of the battery charging stalls and reseated my battery. I bought this tab 2 weeks ago used and this is the first time it has charged to 100 without me forcing it too! Its def worth doing if ur battery stalls!!

I suspect an app did this too. I was on cm when it started...others were stock. Chrome or some other common Google app put our tabs in a funky state.

May I ask why you suspect a drain, like how long does it last and also what's wrong with the built-in bat-stat?
My biggest recommendation is to avoid DL'n every single app and keep it to a minimum.
Mine last roughly 2days with a screen time of 3-4h without charging (was away a weekend recently and took my chances and left the charger at home, used the camera alot incl. 4k shooting and alot of music videos playing and made all the way home with 1 percent )
Best phone in terms of battery I've come across yet.

on the stock rom and kernel?

Hello, what's your android version and firmware build number? I would like to use it because i'm on 4.4.4 build 14.4.A.0.108 and I'm experiencing fast battery drain.

Changing ROM will not help in most cases if you won't discover what is eating battery.
I am on the same above ROM and kernel and I don't complain.
Term 'fast' is not much precise, either.
BTW:
1.3%/h is pretty reasonable if phone was in use from time to time.
Base rule with BBS is to check batery over night, when it is not used at all.
Under those circumstances you should see 0.1-03%/h and that is completely fine.

As always - check that all automatic synchronizations are off.
google, pictures, facebook, whatsapp.
Hope you don't use WiFi all the time, nor you scan for available networks.
BetterBatteryStats is really helpful, read corresponging thread.

i dont think using wifi and auto sync will drain my battery from 60% to 6% in just a second. Anyway, i ordered a replacement battery from witrigs. Hope this fixes my problem. Ive tried factory resets and repair through pc companion. still no improvement. Turning stamina mode improves my battery. It no longer drops 50% in a second, just 10%. Still way too low compared to my excellent battery life with kitkat. Before lollipop, i charge my phone every 2 days with heavy use. Now, i need to charge it twice a day with moderate use.

If so - I'd come back to KK before replacing battery, if for no other reason then to prove LP is guilty.
BTW:
Long ago I decided not to upgrade to LP.
Looks like evey step ahead is in real life step back.
Everything is more complicated, wants more maintenance, yet works worse than old simple tools.

I have a problem with... When battery drops down to 15, my phone turns off, and 46 six aps are being optimized. I'm not alone with this problem, my friend with HTC... has the same. Any solutions?
And now "com.google.process.gapps has been stopped and i must do hard reset.

The battery meter isn't that accurate, its just an estimation based on the battery voltage versus how you use your phone (and the resulting "typical" battery drain). You shouldn't expect it to be accurate to the being within the 1-2 (or even 5) percent range. Shutting off at 4 to 11% is not unusual, and not surprising.
You shouldn't be draining your battery down that low on a regular basis. Its bad for long term battery life. Good rule of thumb for Li ion batteries is short and frequent charge cycles.
However, optimizing apps and/or google process stopped after a shutdown (due to low battery) is not normal. That's a different matter.

I have this problem, plus some of my settings get reset such as my wallpaper, ringtone, notification tone, boomsound (off to on), screen timeout, screen brightness, whatsapp (keeps asking me to chose my backup options and no messages come through until then). This has never happened before and I'm not sure why it's only happening now. I'm not purposely trying to drain the battery or anything, it's just that sometimes on the road I am unable to charge it and it'll just die out midway when previously, that extra 15% could've lasted me for another 30 minutes, just enough for me to reach my destination.

The same problem.. But the bigger problem for me, it's reseting my settings..

It is a terrible problem , I return to KitKat and my battery reaches 1% , and so normal ... I'll make a test with lollipop .

Yes, same problem! So glad someone made a thread for it. It's frustrating and happens literally every time.
Experienced on both the stock and a custom rom. Any one knows any fixes? Is it because of the 'battery life reduces over time' thing? My phone is 2 years old now

That seems to be a problem with all htc ones (m7, m8, m9) as they get older, dont worry its normal :laugh:

ive been experiencing this for a while, clear dalvik cache and let android do the whole rebuilding thing at the start and you should be fine...as for the battery fix ive just learnt to live with it, 15% is the new 2%!!!

I'm on this problem since a lot of time, as i was one of the first in the community to report it.
Seems like an end-of-life issue for one m8 and htc one phones line.
In my case i had a camera and charge board issue too, so in rma htc changed them, and now the phone is charging and quick-charging like it must have to. But i have to be careful when near 15% of battery because using camera, flashlight or others power-expensive features instantly turns the phone off, causing a database mismatch on the next boot (for marshmallow) and consequently the loss of data.
If the instant-poweroff occurs during boot, there is a massive loss of data and a lot of force closes on the next boot.
Nothing to do here i think, sadly.

In kitkat and lollipop battery reach at 1% ...

I have a fix for this as it happened to me and I tried a battery calibration app from the app store... I thought what your thinking now but after finding bad sectors and "repairing" it did actually work

solve the problem of battery and loss of settings , change the battery of my htc, now everything is fine , 3 days that the battery is discharged properly , I hope this information will help someone.

thats kinda "cool" to see many people have same problem as i do. atleast it wont run u crazy as before
1. sometimes phone dies when battery is 15%, and sometimes it dies when around 4% 2% or even 1%
2.resetting settings after phone dies!
so is the solution, to change battery? any better way that doesnt need to spend money?

Yes I've done this a couple of weeks back. The replacement is actually less hard as it seems.
But finding an original replacement battery seems to be pretty hard - Even though the replacement I bought is HTC branded and looks genuine, I feel like it's actually draining a little faster than my old original. 12€ Ebay had too good to be true.
However the instant-shutoffs are now a thing of the past along with the database corruption, so I'm going to have to live with a little less battery life.
Or does anyone know of a provider for genuine batteries?
