i don't think it's bump charging because in the article he says must connect charger and Disconnect sex time so the device received a hefty bump charge.
[Desire General] erklat:
That is false.

He said he did thorough bump charge by doing it six times, not that you have to do it six times for the procedure (which is the same) to qualify as a bump charge.

My phone turns off at 13% battery. I even tried calibration as described in the first post, but it didn't fix this issue. Does someone know how to fix this?
[Desire General] jayknight71:
Gave this a go and seems to have helped. Before I reset battery stats I noticed that my desire never went to a green fully charged led..

Hope I get better battery now. Thanks for all the help on here it's invaluable.
[Desire General] FastPete:
Thanks for this. I have seen a definite improvement over the last few days. My desire barley lasted a day before!
[Desire General] Aksaif:
Safe level.

Hi all,

I am thinking of doing this today.

Does anyone know what a safe/good voltage is?

I am wondering if I should do it if I already have a good level, but I am not sure what a 'good' level is.

Thanks all.
[Desire General] ooie:
Thanks, this did the trick :)
[Desire General] Aksaif:
Did it last night and it worked.

Unplugged it this morning (9am) and it was showing 4197 mV. Started using the MP3 player strainght away and it stayed at 4197 for over 20 mins! (I stopped checking it after 20 mins so im not sure how long it stayed at that)

Been using it all day.. mp3 player, internet, some games and texts/phone calls

it is now 23:30 and the battery level is at 41% (3771 mV)

Good stuff.

I used the hidden testing code to check the levels..

Type *#*#4636#*#* and it gives you loads of info that you dont normally have access to.

Thanks for the calibration info. :)
[Desire General] Yekxmerr:
I dont recommend this to anyone what this does is to overcharge your battery and eventually kills it. What you can do is fully discharge your battery take it to 0% and then take it off from the phone and leave it 10-12hours without any charge ( this will discharge the remaning battery ) after this fully charge it to 100%. After it reaches the 100% take the charger off and plug it again. If its green its ok :)

And if you want calibrate it with great precision you use this method and after it reaches 100% discharge it again to 0% and charge it again to 100%.

Google it and you'll find similar info :)
[Desire General] jm1973:
Hi..

I just tried this battery calibration as follows:-

1. I charged to green LED while phone turned on.

2. Turned phone off and charged again.

But I have a problem...

When I turned phone off, I waited for 5 hours while it charged with LED orange, but it never went green.

However, when I turn off and start to charge phone, it immediately goes into Recovery. So technically the phone is not off?

I have tried several times, but as soon as I start charging with the phone turned off, it boots into recovery.

Is this right? Or should it stay off?

I get very poor battery use, and I turn off sync/BT/wifi/3g/mobile data etc.

Help please?
[Desire General] jesp3739:
Same problem here. Anyone with a solution?

Thanks in advance :D
[Desire General] csizi12:
Try to wipe battery stats in recovery after a full charge. Maybe your batt stats are completely bad.
[Desire General] daniel_pt:
Hello everyone...

I have a issue kinda like that one about chargind the battery

When I do the full charge with the device ON, the led goes from orange to green after a couple of hours.

When I do the 2nd step, recharging with the device OFF, the led never goes from orange to green. I let it with the adaptor connected for more that 12 hours or so, but it still never changed the state...

Could it be that the battery stats are completely wrong or can I have a damaged battery? I guess I need some advice from people more advanced into this phone to help me out with this issue.

Cheers! :)
[Desire General] Godracos:
I just noticed that my Desire battery lasts longer when it's at 100% and not on 98% or something like that. It discharges when it's some time on 100% and strange enough the battery drains in general faster than if I unplug the phone when it's still on 100% - and no, I don't mean the few % less from the start on when I unplug it.
[Desire General] vis-tec:
I thought i would share my views.

I first did this about 8 months ago on a unrooted phone. Couldnt tell a great deal of dirrerance but my phone was only 4 months old som maybe not required but battery level was accurate. Now my phone is rooted i find that issues have become apparent. Including shutting itself of at 15% sometime higher (although it was still on at 4% the other day) and for the first time the other day indicating fully charged at 96%.

Anyone else that is suffering from the phone swtiching off at 15% - Are you rooted?
[Desire General] mouseandcat:
same/similar problem. i got the warning aroudn 15%, i was out, so couldn't charge it. i connected it to my macbook (2,1) aroudn 10% and came back an hour later to find it turned off.

could'nt get to turn it on (same problem as some mentioned, boot for 2 seconds (bootscreen + vibrate once or bootscreen + vibrate 3 times, no led when pluged into the computer or laptop; tried leaving out battery to clear memory, plugged into wall for 8+ hours, still wouldn't do anything but flash on then off immediately).

went to the sprint store and just said the battery for my evo died. the person didn't ask any questions, only said, "i'll get you a new one." i asked if it would be new oem or refurb, said it would be new and immediately went back and got me a new htc oem battery.

i then asked them to check my old battery on a codex machine, they said it was "good" and charged it to about 54%. tested the battery in the phone and it worked just fine.

[Desire General] getan:
I'm not sure if it worked with everyone but it didn't with my Desire. But I'm getting used to the two day battery life I got. I plan to buy an extra cable to put at work just in case.
[Desire General] deboned:
thanks will try this
[Desire General] hmhm:
Thanks! Works great.
[Desire General] civilian_pr0ject:
hey guys i tried this last night on my desire hd/inspire 4g.

my method was drain till it dies, reboot and let it die again, then charge all night in power off mode. here is the problem:

when i start charging the phone automatically boots into clockwork recovery. i tried to power off but it always does. i let it charge all night in recovery. does the completely defeat the purpose?
[Desire General] Dread This Day:
Just thought I would tell you all that fully discharging your battery is NOT a good idea. It will PERMANENTLY kill battery cells. Im at work and don't have a source for you, but just use Google.
[Desire General] undercover:
You have to try really hard to discharge battery FULLY. Even when phone shuts down there is still some charge left.
[Desire General] spdrosin:
I read in a forum that battery stats wiping should be done when battery is almost down. Are you sure that this should be done when fully charged (at the calibration procedure) ?
[Desire General] dishko:
I did wipe the stats when battery was almost drained, and for now i have perfect results.

Same usage as always, couple of emails, couple of IMs, one message, and its been almost 2 hours, and battery is at 100%.

Will try it on other android device, to check if it`s gonna work.

Thanks.
[Desire General] dishko:
Checked, Motorola Milestone (Droid) shows pretty much the same effects.

I never thought this would be so effective.

:)

Great!
[Desire General] puntchiel:
Darn, it works the other way with my desire (GingerVillain 1.8 + Amon Ra) . I did the procedure TWICE today but my battery has dropped to 90% in a little more than HALF AN HOUR!

This is what I did:

charge with device turned on untill green led

unplug, turn off device,

plug in and charge untill green led

unplug, turn on device, wait a couple of minutes,

turn off and charge untill green led

Wipe battery stats in recovery

This didnt seem to work so I tried it again, only without wiping the battery stats after the procedure.

I'm not sure if I wiped the battery stats before flashing the ROM, however I did do a complete wipe. I figured it wipes the battery and dalvik etc.

Before I tried calibrating, the first 10% of my battery took about an hour or so (depending on usage), and it turned itself off at about 7%. Pretty anoying as you probably all know :p

Does someone know what I should do? As you've probably noticed I'm pretty much of a nub in this scene.

Thx in advance!
[Desire General] Tuxi91:
Worked like a charm, thank you :)
[Desire General] navdra:
I would need really good reason to do this.

Maybe it's best not to fiddle with battery as long as it works reasonably well.

Thanks for making it easy anyway!
[Desire General] Bouncer5:
Since I've had my phone for a year now, I've got a better idea now, I will go back and edit the post with updated instructions, Stay tuned!
[Desire General] cevacu2005:
significant improvement.i did it yesturday,i played today for a full hour on my desire, wifi on all the time and i still have 29% of juice left.my battery never lasted a full day.works 100%
[Desire General] undercover:
Which post is that mate?
[Desire General] Bouncer5:
*Derp* Didn't mean on here :D
[Desire General] Jilke:
A did calibrate my battery by that instruction on the first page and Im still having this issue : Phone dies on 10% when I charge it and its on 90% its skips to100% and says charging is done. Is there any way how to fix this at home or should I reclaim? Thnx
[Desire General] sohlican:
It doesn't work for my Incredible S. Lost 20% after 1 hour of standby. :(
[Desire General] ahac85:
i have the exact same problem, is there a fix, i think we get 100% use, its just the battery indicators are reporting it wrong, because if u use a battery widget it shows phone shuts off at 3.600mv and is fully charged at 4.201mv
[Desire General] spdrosin:
How often should we calibrate the battery? Once per 3 months maybe?
[Desire General] fragargon:
I guess you should do it only when new rom's is flashed... (from my own private though it makes more sense)

however i've never flashed de battery stat while it happens few times that the battery drain a lot on half day... each time i have looked through the logcat which reveal some error (unidentified... so I reboot the phone)

an app refused to freeze so it keeps the proc awakened (i use quick sys info to do so)

the phone used to get average of 70% when i get home 10 hours after charging and normal usage.

meanwhile those argument did you know that an xda dev make ann app for this call battery calibration ??

hope this would be helpfull ;)
[Desire General] cez10:
did the method from post 1 and can say that it does work :)

after 4:30h with about 10mins phone calls and wifi on all the time i still got 100% :)

mobile network is the biggest enemy of the phone battery :/ as soon as I switched wifi off and switched mobile net on 5 mins later it went down by 1 and then after like 10-15 mins again down by 1 :/
[Desire General] vinilopes21:
good to know
[Desire General] kmetek:
It must been when i rooted my Desire while plugged to PC....

Ok I'll wipe my stats then.....hehe

Hopefully will be corrected then :P
[Desire General] forelli:
Thanks a lot to the OP, it's very useful, our Desire are very nice and powerful, and very power-hungry too! :)
[Desire General] alex_hk90:
The full process outlined above involves wiping the battery stats, but from my experience that part isn't strictly necessary. So definitely calibrate the battery and if you want clear the stats as well to be safe. :)
[Desire General] Lennyuk:
You only need to do this if you flashed a rom while the usb cable was in AND have a reason to think your battery life has since got a lot worse.

Remember the desire battery is not fantastic, and underclocking makes it a million times better, calibrating might not be what you need.

Try charging to full, then powering off and plugging charger back in, if it goes green straight away then your battery levels are fine, if it goes red for a bit 5 mins or longer again then you will need to calibrate.
[Desire General] KBanause:
That's the way my phone had behaved :)

I hope it will last longer now.
[Desire General] vidler:
So combining the two bits of info we've compiled, the best way to calibrate your battery is as follows

1: Charge phone whilst on till LED is green.

2: Disconnect phone from charger, power it off.

3: Reconnect to charger with phone powered off and allow to charge till LED is green.

4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.

5: Reboot into recovery (back button held at same time as power button) and wipe battery stats.

Battery should now be calibrated.
[Desire General] kmetek:
vidler: you mean charge it twice in a row? Did you read it correctlly? I believe only 1 time.

**** you're right.....it needs to be done twice.

1. 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.

2. 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.

3. 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.

4. 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.
[Desire General] DesirableHTC:
Right, there cant be just me that is having this issue. When i let my phone charge to full (LED green) then disconnect and power off re-connect to charger until light goes green again, but the light is already green as i have just charged it! This is my issue so what do we do? :confused:

Sorry, i didnt see this post.....
[Desire General] gregounech:
Let me recap, do we have to

Charge while it's ON

Power OFF, charge it while it's off,

Power ON, charge it again till Green LED

THEN

Wipe battery stats or not ?
[Desire General] marinierb:
Do you have BT on? I leave mine on all the time because I don't want to have to deal with in when I get in the car. Set and forget and all that. But it seems to eat up a lot of battery.
[Desire General] misterdev:
I followed the instructions 4 hours ago.

My battery still shows 100%...

I did not use it a lot but it is still awesome !

I will see if it drops to 90% in just a few minutes or not.
[Desire General] Dany0:
Charged till 8:00. From then a little NFS:Shift and few mails. Should I be amazed? Using interactive governor...
[Desire General] Timar:
Wich is the right way after all ? :)
[Desire General] Lennyuk:
My way is the way its been done on other android devices for ages, and is the way most widely reported to work. :)
[Desire General] shoonari:
I always use next method:

let your device die due to low battery

take out a battery

wait 2 mins

insert battery(do not turn device on)

connect to wall charger

charge ~8hours

take battery out and wait 2 mins again

insert battery and start using your device

works perfectly during 5 years with lot of devices(qtek s100, arthemis, diamont etc...)
[Desire General] EddyOS:
And for non-rooted where you can't delete the battery stats? I'll try it anyway just wouldn't mind giving it a clean start...
[Desire General] DragosP2010:
Wipe, but you have misunderstood the calibration procedure.
[Desire General] perettigiuliano:
Excuse me but... it's a little a time-waste method... i am trying the other one and till now (charged 2 hours ago) it is working!!!

Bye..:D
[Desire General] umd:
After power off, I plugged the charger. Notification led is always green. Never red before green. Is this normal? Do I need to calibrate again?
[Desire General] pa.pn2:
so if i changed my rom and had my usb cable in, i have to calibrate everytime?

right?
[Desire General] spdrosin:
I think the calibration gave me a 10-15% more. Nice, but I have this issue/bug: 100% (0mAh) lasts only for seconds after unplugging the charging cable that means that real battery drain starts from 99%. Why is this happening?
[Desire General] jannen:
Come on guys... you can't be seriously saying its working, if after hours of usage it still says 100%!

This calibration messes the readings - don't give any extra juice out of the battery.
[Desire General] cez10:
not really 'of usage'

as i said i had wifi on all the time, made a call lasting 5-10 mins n send few ping chats n it lasted 4:30h, then switched to 3G and went down like mad
[Desire General] killingflowers:
Found an app today called batterycalibration (rooted phones only) on the market. It's gotten some pretty good reviews.

Don't know if it'd work, I tried the methods posted in this thread but to no avail, so I'll let you know how I get on.

Hallo by the way! I'm new in this forum. Must do a signature thing and whatnot.
[Desire General] cad_2011:
thank you. downloaded it :)
[Desire General] killingflowers:
Lettuce know how you get on. I'm following it to the T
[Desire General] aswinarun:
It says it will replace the battery stats file, but in my case it didnt provide me any results... it is the same.. may be someone could elaborate the findings
[Desire General] killingflowers:
Didn't see any improvement whatsoever. Driving me mad, the battery isn't lasting at all for me, around 8 hours.

Out defiantly isn't a background app, I rooted recently and am running gvillain 1.8 (haven't updated yet) and have been selective about the apps I'm installing.

Any thoughts?
[Desire General] undercover:
Maybe knackered battery? Have you tried changing radio and ril?
[Desire General] welshyoot:
I've downloaded this and i'm waiting to see how it works.

Tried the method in the original post and also have updated permissions in rom manager so will see what works!
[Desire General] killingflowers:
I haven't... I'm reckoning on getting a new battery; howevers, I've seen this 'updating the radio' business, but not quite sure what the point of it is... Could you explain? That'd be lovelyness personified.
[Desire General] killingflowers:
Super duper. Let me know if you managed to tame that battery of yours. Mines is running down quicker than the tears on my face everytime I look at my phone and it says '65%' after being removed from charge 2 hours before.

(That was quite an elaborate analogy of something running down; there really was no need for it, or this explanation explaining about the pointlessness of said analogy... Terribly sorry..... Sorrier than when I look at my batte... nevermind)
[Desire General] cez10:
I dont think it works that well, unless you do it everytime which I doubt is recommended...

first time I tried, I had 100% for about 4-5h with few mins of calls, wifi on and few ping messages, then switched on the 3G and battery went down every couple mins, now after a few normal charges (phone ON while charging from about 10-20% to 100%) and the 100% never lasts as long anymore, the battery seems like its how it was before I did this method :rolleyes:
[Desire General] rkuijpers:
Personally I think this app is crap(p)...
[Desire General] Borat38:
Updating the radio and its RIL is supposed to make the phone have faster refresh rates, get more adept at signals, etc.

I flashed a new radio and RIL alright, but the best insurance against poor batt life is still what I did: bought a portable fast charger that I always bring with me. It's nearly as small as an HTC battery, with a charging cord. And since it's got 2,100mAh capacity, that effectively brings my batt power to 3,500mAh. Not bad!
[Desire General] killingflowers:
Hmmm. Interesting. I may try doing this to my phone. I've also got a new battery, to see if it helps with my battery woes.

Have you a link to that loverly sounding ext battery? Sounds delicious.

Ta.
[Desire General] ahac85:
ive had this problem for a long time the phone indicators reporting the wrong % and suddenly one day my battery started shutting down at 0%.

What i did was erased battery stats at 100% then let the phone run untill the the battery was completely flat (this was usually the desire switching off at around 10%), then leaving it on charge whilst switched off overnight, the next morning boot the phone up with the charger plugged in and once the system was fullyup, unplug the charger, then use the phone as normal untill it was flat again, and repeat the process all over again but this time there is no need to wipe battery stats, and hopefully the procedure second time, will make the phone switch off at 0%....well it worked for me so i guess its worth a shot.

....just to clarify when your phone shutdown at ~10% you have not lost 10% battery, ur battery indicators are reporting the voltage incorrect, the procedure mentioned above suprisingly fixed the problem on my desire. you may use an called Battery Monitor Widget to view battery activity and its free, theres a graph that shows battery stats.
[Desire General] Borat38:
It's a portable charger, not an extra battery

It's not actually a battery, it's a portable charger. It's just slightly larger than an HTC batt, and has a charging cable that has interchangeable charging pins, so that I can charge not only my HTC phone, but also iPhones/iPods, Blackberrys, Motorolas, Samsungs, Nokias. I bought it off the shelf in Hong Kong. I've attached a picture of it here.
[Desire General] Borat38:
Ok, the manufacturer is listed on a business sourcing website: http://www.alibaba.com/product-gs/379693429/Universal_portable_mobile_battery_charger.html

I think having a portable fast charger like this is much safer than trying to use an extended-capacity battery. The risk of the extended-batt leaking or exploding is lessened, as you're only carrying a charger.
[Desire General] killingflowers:
Yarp. I used a power monkey for a bit, but was a bit concerned it looked slightly like a sex toy... But it was grandios. Does the trick, especially when I'm out and about.

The new battery is no different. Still ridiculously poor.

Shame.

Actually to the point where I'm considering the new nokia e7. Heard it's a peach when it comes to battery life, and functionality.

I used to use nokia's symbian since the original 6600, then the n range, moving swiftly to the e range, so I suppose I've been spoilt with brilliant battery life.

Absolutely disgusted that nokia didn't go the android route; the brilliant hardware coupled with the amazing software would have made a device sexier than a lady stepping out of the mediterranean sea, only with w7, it's a hairy tubby bloke falling out of the atlantic sea after stepping on a pointy stone, and picking his belly button, then sniffing his finger.

Sent from my HTC Desire using the little charge I have left in the battery.
[Desire General] Borat38:
^Me too, coming from more than 10 yrs of Nokias, I'm never going back until they do an Android phone. The Finnish absolutely made a big mistake not capitalizing on their mid-end phone segment strength by installing Android.

It still baffles me how Nokia could manage such sturdy batteries with Symbian (also many smartphone capabilities), while HTC can't with Android.
[Desire General] killingflowers:
I've been looking at this new symbian software; seems hard to whack to be honest.

I may be getting my mits on one tomorrow, so I'll let you know.

(i apologise for this thread going slightly off topic... My next comment should remedy this)
