[Q] New battery from T-Mo, how should I calibrate?

Just got a new battery from T-Mo today, as my battery life has been depressing since 2.3.4 update a month ago. With the old battery, I tried 5 cycles in a row of fully discharging, and fully charging while off. No difference, Juice Defender, m a y b e a little difference...been searching around for an hour, and remember a few things from reading XDA over the past month. So many different techniques, most for rooted phones, mine is completely stock(and I do plan on rooting soon still researching/learning), 1st thing I did when I took it out of the mail, was put it in the phone, and charge it while phone is off. Green LED has been on for 3 hours now. I'm scared to turn it on!! How do I calibrate this baby and make sure to the best of my ability this battery stays good?? Sorry for essay on one question.

wow, 56 views...0 replies. Nice.
I read one of the MANY threads yesterday on this, a guy said to someone, something along the lines of..."use the search, there are countless threads on this...and you can find this, like I did"...
This is what he said.
Charge the batt all the way while off(wall), then unplug, plug back in, light will be amber, then change to green. Repeat this process till The amber light doesn't come on anymore.
SO, I did this...about 100 times. It would go amber, blink, amber, then to green with no blink. Then sometimes it would go amber, and blink to green. back and forth. Seriously about 100 times. It never would initially light green. Amber everytime.
So I finally gave up, went to sleep. Still getting mediocre battery life today.
Where is help when you need it??

Drain it until it turns off, plug in, turn phone back on and let it charge to 100%, unplug, drain until it dies, repeat process 3 or 4 times. Download calibration app from market and use it when 100 % is reached.

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

That was the official reply from HTC during the EVO 4G days

So instead of fully charging while off, fully charge it while it's on? And, the calibration app, is this a general statement, like any app, or a specific one?

It's called Battery Calibrator. This is the process I found on the forums, it works, on stock battery I average 5 hrs screen time and can get over a day on one charge. On the Anker I get even better, I have been methodical about conditioning batteries and I am getting great battery life.

Yo, when u see that green red led combo, know that your phone is telling u that battery is overheating/overcharging. It's colorful for a reason, telling u to stop.

It is not red, it's amber(orange/yellow) And it was on this thread that I read to use that technique - http://forum.xda-developers.com/showthread.php?t=1139092
He says "use search, it can only help you"
well, like I originally said, I have seen numerous techniques on calibrating. Just trying to find a solid one. That guy @KillaHurtz had a lot of thanks and seemed to know what he was talking about, but like I said, I tried his technique 100 times and couldn't get the results he was saying "repeat until no amber light showing", and that was after leaving the phone on charge(while off) 3 hours after it already turned green.
So one says, do this...another says...that is overheating/charging your phone....
are you mistaking my amber for red? I seriously hope I was not damaging a brand new battery before even turning my phone on with it.

Apple recommends this: http://support.apple.com/kb/HT1490
1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
4. At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
5. Turn off the computer or allow it to sleep for five hours or more.
6. Connect the power adapter and leave it connected until the battery is fully charged again.

Rhiannon224 is right. I don't repeat the process 3 or 4 times like she does, but once a month I let my phone run down until it turns itself off. Then I leave it off and charge it overnight. I get better than average battery life, although I don't get 5 hours of screen-on time with the standard battery or with the EVO3D battery (1730 mAh). I easily make it through my normal usage for a day -- 20 to 30 emails (gmail and HTC Mail app set to push), facebook and weather sync every hour; Plume sync every 30 mins, 20 or so texts, 15 to 20 mins of phone calls, some Slacker radio, short sessions of Cordy or Angry Birds to waste a little time.

Hah, sorry for the late response. When I said red, I was referring to amber. There are only 2 LED colors for the Sensation. Have you tried disconnecting the charger, turning off the phone, then connecting again? If it wasn't at full cap, it'll go back to being amber. Do this too many times, you'll notice it'll start flashing green and amber, signalling that the battery is getting overcharged.

If your phone is on and charging and you get say a text/email or other notification, you will get the green/amber flashing as well. I'm not sure if the battery is overheating of it will flash multiple colors or not however owning a sensation I can tell you from experience that my phone has been hot to the point where it is uncomfortable to hold charging or not and the only time I have seen an orange/green flashing combo is when it was charging and I had a notification. Orange by itself means charging. Green by itself means fully charged. Hope that helps with the confusion. For the battery life, if your phone is rooted, I recommend using faux clock to manage your CPU levels and keep your battery life up. If not, try lowering the brightness of your screen in order to make the battery life last longer. My phone gets me through a full day without charging (pre and post rooting) and I'm on it quite frequently and all I do is use my phone as usual and drain it until it dies once or twice a month to help prevent the "memory effect". Hope this helps!

[Q] Is my phone dead? :(

1. The phone won't turn on
2. The charging indicator doesn't light up when I try to charge the battery.
3. One of the sensors on the top left turns dim red in color when I connect the charging cable
4. I can't hard reset either
thanks

Did the battery die all the way? Or did you flash a radio without checking the md5? If its a borked radio install say hello to a 500 dollar paper weight if its the battery your gonna have to charge it in another phone cause I'm not sure if cwm 5.0.2.7 has powered off charging

Yes we need a couple of info first. Also we need every information we can get in the last events before the phone got bricked. Like what did you do? what ROM? What's the status of the phone? Battery?
The more the details the better we could assist you.

Sounds like when my first Mytouch 3g broke, it would turn on the first couple of times going into a bootlope at the HBoot. It also didnt respond to charging or any other battery i tried.

Thanks for the reply strapped. I haven't flashed a radio. I did flash the virtuous infinity rom though. I'm not certain if that affected the radio. I did, however, let my battery die all the way. Do you know why one the sensors on the top left corner turns dim red when I connect the charging cable?

Oh crap the battery die all the way problem
I think your battery is dead.s
Saw dozens of problems like this on the my previous device's forum.
Li Ion batteries have this fuse inside it in which it trips off when the battery gets discharged to a certain voltage. If it does your battery goes into a suicide mode in order to protect the phone.
basically the best thing to take good care of your battery is not let it drain lower than 40% and not fully charge it to 90%.
discharging it too low drains it's lifespan drastically. While charging it too high also drains it's lifespan.
Over-discharging Lithium-ion
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.

Cheers guys. Here's every bit of information I can recollect
A few days ago I created a nandroid backup and formatted my sd card via the PC.
I flashed the latest version of CWM recovery
I flashed the virtuous infinity rom 1.33 alpha v3 and then flashed the 1.35 beta 1 update.
Then i copied some music on to the SD card and installed a couple of apps.... nothing out of the ordinary.
The phone worked fine the last couple of days but I don't remember letting the battery die all the way. I should add that I have a dodgy battery; a couple of months ago my dear girlfriend spilled her drink and beer went in to back of my phone... since then the keyboard doesn't work (some keys work but its basically dead) and the battery has been affected as well since it now only lasts 3-4 hours after a full charge....but this issue can't have caused the problem I'm now having because the dead keyboard and dodgy battery have been around for a few months...
Last night, however, I think I let the battery die all the way and at some point, when I tried to turn it on, the phone vibrated as it does when you hold the power button, however, the screen didn't turn on. Since then, nothing has changed. When I connect the phone to the PC, it makes a couple of "connection" noises but I can't access the SD card or contents.

by saying latest CWM is it the 6.0 touch based CWM by chance?

sorry mate, i meant 5..0.2.7.

That's the CWM I'm using so it's safe. I'm also on latest VI for weeks without problem.
So it all points out to your battery.
Phone vibrating to power button means it's responding perfectly. Not sure about the light on the sensor only htc technician can tell.
But what I can say is if your trackpad button lights out red always then you got a brick on your hand.

Nope the trackpad isn't red so I guess that's a good sign. I've ordered a new battery and should have it later this week. Let's see if that fixes the issue. Will report back. Thanks all!

So, a new battery has arrived, however, it hasn't helped as the phone won't charge (no orange light) or turn on...... Since I live in Australia, I don't know anyone else with this phone. Is there any other way for me to revive my brick of a phone?? Thanks

Get a universal charger for your battery.

This is a rough situation. Even with my DS I've had situations where nothing would happen when I tried to restart it, in particular when I let the system run all the way down. It is as if the battery needs to have some charge for it to charge more. I have three batteries though (the stock & two Anker 1900's) so when this happens I just swap out the battery with one that I charged in the external charger, and I haven't had any real issues with them long-term. Since you bought a battery, what battery was it, and do you think it was charged when you got it, and do you have an external charger to verify that the charge is solid when you put it back in the phone? Your phone may be completely dead however, but at this point, I don't think anybody on the thread really can tell. This make sense? I don't want to say, "buy a set of Anker 1900's with an external charger" but it was cheap enough vs. the cost of the phone, and the DS does seem to be a good one overall.

Hi All,
So I got an external charger for the battery and it arrived yesterday. I then proceeded to charge the battery and hours later, no luck. The phone still doesn't turn on. When I hit the power button, one of the sensors on the top left turns red slightly, shortly after which the phone vibrates. However, it doesn't turn on.
Where do I go from here?
Thanks

have you tried to disassemble your phone at all? you said liquid was spilled in it, could take time for corrosion to turn up. maybe a little electronic parts cleaner or rubbing alcohol may help out

Nope I haven't tried to disassemble it yet but is that the only option remaining? If yes, I might have to give it a go because this phone is now as useful to me as a brick, in its current state.

galaxy ace not charging

I don't know what anyone means by all this 'download mode' and 'recovery mode' etc, I got my phone last month and I am new to it.
The battery life has always been quite lame, but this morning I was charging my phone and it was on 5% according to the battery widget.
Then it turned off, and now it won't turn back on.
It comes up with an empty battery but instead of the green bar moving to charge it, it is empty with a yellow triangle with another battery inside with a line going through it!
I have left it alone but it vibrates every five-ten minutes spontaneously, and occasionally shows that empty battery again.
I have tried removing the battery then putting it back and charging it from different sockets/from my pc - nothing is working.
please help me.

[Q] Battery charge indicators show different values when phone is off or on

Hi. I searched for an answer to this weird problem but couldn't seem to find a similar issue. So here it goes.
When my phone is off and I plug it to recharge the battery, after a due amount of time (or even the whole night) the indicator shows a full green battery and states 100%: fine. But ... as soon as I turn the phone on, the percentage indicator in the top right every time shows a figure between 82-84%. So I need to plug the charger back on again (this time while the phone is on) and after a while I get the 100% on the indicator.
This has happened since I bought the device and with both my (new) batteries. Pointless to say, I did try to reset the battery stats a number of times to correct the issue. No joy.
Am I the only one experiencing this? Any clue on how to fix this discrepancy? Granted it's not a big deal, but still a little annoying.
Thanks
Mike

What might be happening is that your device uses a lot of power in order to boot up. 16% of battery life seems a bit strange though.
The other thing that might occur is that the threshold for the green light to be lit is at about 84-86% (meaning: if the battery is more than 84% or something charged, show the green light).
What I suggest doing is just leave your phone on all the time and perhaps reboot it only when necessary.
As far as I know, there aren't really any solutions, but maybe you should try contacting support from the manufacturer of your device. Perhaps they know more about the subject.

Thanks exenia121,
It's definitely a weird thing. And i was more curious to know if I was the only one to report this. There must be probably a strange surge on boot up. In fact after the recharge of the phone (while being on) was completed (100%) I turned it off. But when I powered it after a couple of hours I was back at 84%. Hmmm ....

Z3 Battery Madness (1%/50%/100% Cycling constantly)

My battery life keeps bouncing between 1%, 50% and 100% and doesn't show anything else, you can be looking at the screen and you randomly see it flick between all three values and even more weird, the battery menu is no longer listed in the settings menu and I have no way of knowing what amount of charge my battery actually has.
This morning the phone went off saying low battery (whilst also saying 100%) and when I turn it back on it shows the low battery symbol in the centre of the screen and does not boot-up, great, the battery must be dead. I put the charger in and the red LED light comes on and battery low indicator come on for two seconds, then switch off and endless repeats no matter what I do..
I left it for an hour doing that and turned it on and used the phone for 30 minutes without any problem, then it turned itself off saying low battery, and started doing another loop of the low battery and red light in standby mode round and round again even though it wasn't plugged into anything. I pressed the reset button and after that I couldn't turn on as just a standard, battery low message.
I did a repair of the phone, which surprisingly was able to be carried out despite the fact that the phone wouldn't turn on because of "low battery" before I did it (which makes me doubt it is low) and the moment I turned the phone on after the repair it was still "Low Battery" and refused to turn on, which is somewhat strange bearing in mind it clearly had enough battery for a repair.
I left it for 4 hours charging and I turned the phone on and it operated for an hour in a factory reset mode no problem, however the indicator cycling was still going on. I plugged the charger in and the sound for charging was made, but the phone showed as not charging, despite the fact it made the sound that it is (I think it is actually charging but nothing to indicate ti is)
Again I go into settings and there is no battery menu there, if I search for it using the hourglass it tells me no battery data is avaliable. I search for Stamina mode and put it in Stamina mode and it refuses because just when I hit it, the battery reader says 1% and it says battery is too low. With some good timing I manage to press Stamina mode when it was on 100% and now it's in Stamina mode with 942 hours remaining,, the phone has been on for 3 hours now and now says 950 hours remaining.
Meanwhile the battery gauge continues to cycle 1%/50%/100% all of the time.
Has anyone seen this before?

I did not have this exact same issue, but Battery menu disappeared and battery would mostly show 50% (and very rarely the real data).
Got my battery exchanged now, everything back to normal now. Might be Sony used crappy batteries (though as long as they don't explode I'm somewhat happy).

I sent it back to Sony and I am now am about to go into a third week with no phone.
For the last week they have been waiting for stock to exchange the phone, since they have no stock (no joke) I am still waiting and they cannot tell me when they will get stock.
The fact a mobile phone company have no stock of phones, is pretty funny.
