Is there a software that control how your battery will be charged?
I know there is a tweak that allow your device to connect to your phone and sync without charging it.
However, I'm looking for a program that will let my battery drain till like 2% before it start charging. The reason I want this to happen is because it'll improve the performance of my battery. It's always good to drain out the battery before fully charge it again.
I don't know about any app that will do that for you, but no charging while syncing can be done in the settings:
settings/system/energy -> Don't charge while conected to PC
Interresting?
You said you want to discharge your battery to almost 2%
Mayby interesting to read the story about Li-ion batteries.
http://www.batteryuniversity.com/index.htm
They say that's it isn't always good to discharge the Li-Ion battery totally.
besides:
Low Maintenance - no periodic discharge is needed; there is no memory.
Good Luck,

That's interesting
Thanks
this is totally wrong
you drain the ni/cd batteries for better performance not the cellularphones.
you drain the cellularphones battery ,potentially kill some battery cells.
drain it to 2% more than 15 times kills half of it capacity and/or age.

i am one of those anal people who likes to keep his battery in good condition by always letting it empty completely before recharging and i have noticed alot that i run into a situation where i need the phone fully charged for some reasion or another but dont have the time to sit around with all the nic's turned on waiting for it to die. i have seen a battery discharge feature on some devices that will rapidly drain the battery to 0 so it doesent develope memory when you plug it back in i was wondering if anyone has made one of these for the raphael?? any links would be apreciated.
i have already rtfw'ed and searched everyone seems so obsesed with prolonging battery life not draining it so i have had no luck
You are actually doing more damage to the battery draining it all the way then if you'd just charge it when you can if you are indeed doing this every single time.
All HTC devices use a Li-ion (Lithium Ion) battery, which do not get a charge memory in the cells like rechargeable batteries of yesteryear.
Instead their life cycle is based on number of discharges and recharges and the batteries age. If you're needlessly discharging your battery and recharging it, you are dramatically shortening it's life.
You should read up...
http://en.wikipedia.org/wiki/Lithium_ion#Advantages
...they may be irreversibly damaged if discharged below a certain voltage.

Like many rechargeable batteries, lithium-ion batteries should be charged early and often.

Lithium-ion batteries should not be frequently fully discharged and recharged ("deep-cycled"), but this may be necessary after about every 30th recharge to recalibrate any electronic charge monitor (e.g. a battery meter). This allows the monitoring electronics to more accurately estimate battery charge.

It is clearly stated in the Fuze manual that it is SUGGESTED that you fully discharge your battery and fully recharge to get the most out of it.
thanks for the advice i will look into it but i would still apreciate someone answering my origional question as to wether or not anyone has actually made one of these apps

This is almost certainly suggested so the battery meter maintains a good calibration. As GldRush points out, you are not doing any damage to the battery or shortening its life by short-cycling it. You could also harm it by deep-cycling it. Allowing the phone to go to 0% is not, however, deep-cycling the battery. For the phone, 0% is the point at which the operating voltage of the battery has dropped to a level that is approaching the lower limit for the board set (with a safety factor included). That's almost certainly nowhere near a discharge level that could damage the battery.
So if you want to let/make your phone go to 0% before every charge you are probably wasting your time (except for the slight benefit of frequent battery meter calibration), but also probably not harming the battery.
After the 2nd battery warning notification comes up, I end up just launching youtube and running a video. The use of 3g coupled with video playback gives me an auto shutdown of the unit with 5 mins or so.
Turn on the GPS. That should drain it in less than an hour.
I haven't seen any discharge apps but I do know that the biggest battery vampire is palringo...start palringo and join a group with a lot of members and your battery will drain at least 20% in about 10 minutes...even if there are no conversations going on you will still get a dramatic battery drain running palringo in the background
Haha, or use an older version of S2U That drains your battery like crazy too.
Way to discharge a full battery within an hour:
- Start Wifi and let it stay on (no need to connect).
- Start Bluetooth and keep it on (also no need to connect).
- Open Google maps and let it use GPS
- Put Google maps in the background and start playing Teeter.
it's almostly no necessary......

These batteries actually get hurt by completely discharging - you're not supposed to do that - you'll kill the battery by bringing it down to 0% too often..
(but to answer you - that's easy.. turn it on.. this phone's a battery hog..)

There's an interesting artice in The Reg about lithium battery maintenance (albeit more related to netbook and laptop batteries).
http://www.reghardware.co.uk/2009/05/07/beginners_battery_maintenance/
not needed, but just run palringo and google maps while listening to music streamed from di.fm in Kinoma. (pretty much what I run day in and out )

this works for me
My xperia only lasts about a day with moderate internet usage, with moderate amount of necessary programs running (I ALWAYS close all apps after finishing).
Just a note, all my data connections are closed & tweaked to close after 2 mins of inactivity.
I heard that X1 batteries should last for ages.. at least 2 days to 4 days.
But I heard I need to flat out the battery, and then full charge it to 100%, followed by a soft reset. Apparently, this recalibrates the battery levels and users have reported battery life extend to 2 days to 3 days more!
So, my question is, if anyone has recalibrated their battery meters is..
1) After flatting my battery out, do I full-charge with the phone OFF or ON?
2) After I have fully charged, can I use PHM Soft Reset after windows boot-up?
Thanks.
I think you should buy another battery if you want more time.
My battery is down to about 50% on average after 8 hour work day. I have push e-mail and IM client and they always cause drain. 2-4 days would be if you didn't have consistent background services running.
As far as what you are saying about recalibrating the battery I think you are misinformed. Xperia has a Lithium-Ion or Lithium Polymer battery. Generally recharging frequently is better for it than doing a full drain. The type of full drain before recharge that you are describing was common recommended practice for Nickel Cadmium or Nickel Metal Hydride batteries. These could develop a "memory" in the battery which would dramatically reduce the amount of charge they would hold before they refused to charge.
If anyone has good evidence to the contrary I would love to be wrong, but I am pretty sure that with PUSH and IM there is no way to get a 1500mAH battery to last 3 days.
Also the radio you use and the area you are in (proximity to towers) can have a significant effect on your battery life.
charge it when it off for - + 1 Hr .
it will saty about 2 days

This is not absolutely true. It's true that Lithium battaries don't develop "memory" problems on their energy storing part, but they have a small circuit and this circuit is possible to develop the "memory" effect. This circuit is the one that decides that battery is full and cuts energy supply or informs about the percentage of the battery power remaining. This circuit for example is the reason that there is no point anymore on having the battery charged for 24 hours when you charge it for the first time.
IMHO you could try emptying the battery and charging it again when the device is off. Don't try to drain the battery completely as it could damage its power storing part.
i think i have the same problem about my X1. when i full charge my battery and after a few hours it goes 50% and sometimes my battery indicator says that i have 80% and after a soft reset the battery indicator says i have 20% weird...
So most people should have heard about currentwidget by now, most people talk about it and use it to see what battery drain occurs during standby mode or airplane mode.
Now I'm sure most know this but incase you didn't, currentwidget helps to ensure your battery is fully charged as well. This is good for people that complain about their battery dropping quickly after a full charge.
You can use currentwidget to monitor your charge, when the battery says its 100% and led is green, currentwidget still shows power going to the battery in form of "ma". I noticed my battery said it was charged and eventho at 100%, currentwidget still showed "ma" is being delivered to the battery . After two hours only it showed 0ma, now I'm sure that means that eventho my phone said its charged, it wasn't fully charged until 0ma were displayed in currentwidget. Since I noticed that, I've been charging my battery "fully" and did notice my battery stayed much longer in the 90-100% aisle when being unplugged.
So if you feel ur battery drops too quickly from a full charge, use this widget to help monitor your charge.
yep, tnx for the tip, im useing clarus battery and its do the same - and i like the widigt so...
the current widget always shows some value of mA . how do we know when the battery is really full ?
Well with me after 1hour at 100%, it shows 0ma. That's when I know the battery is completely full and reached its maximum capacity.
I don't think waiting for the battery to get to the 0mA level is good for the battery performance. Usually the green LED comes on when the widget shows 50mA.
A high-charge concentration for a long time in a Li-Ion battery is bad for the battery. Thats why mobile phones have a little buffer to stop the entire capacity to be full, and try to lose the first part of the full charge as fast as possible.
Since i use some RC Helicopter with li-po/li-ion that both have the same way to produce energy, I have learned how to use this kind of battery and how to ensure a good battery life/durability.
There is no reason to worry about the battery if you follow those few recommendation (given by a battery producer):
-Your battery has to be charged with a current of 1C max (1C mean 1230mA for a 1230mAh capacity).
-Your battery voltage must not be over 4250mV. If you go over, you may damage the battery and risk random explosion/fire. In normal use, it's better to not go over 4200mV.
If you charge the battery with your phone, you will never be able to go over 4200mV because the charge stop automatically before.
-Your battery must not be under 3300mV. Same risk as above. In normal use, it is better to not go under 3450-3500mV to ensure a good battery durability (numbers of cycle charge/decharge). I think the phone show 0% at near of 3450mV, but never check this cause i never wait my phone to be as close to the death.
-Your battery has to be drain at a current of 10C max, i.e for desire HD , 12.30A (1230mAh x 10).
impossible to reach that current with your smartphone so no worries about burning your cpu with heavy bench.
Whatever you do respecting this will not be harmful for your battery.
im just wondering if i should drain the battery of my nexus before i recharge the battery or is it enough to recharge if it prompts (like 15% battery life and below).
when is the best time to recharge to extend the battery life?
Just plug it in as and when really.
In terms of battery shelf life, I doubt it matters as long as you don't do a bunch of short charges that waste charge cycles. In terms of how much battery life you'll see from your phone, let it drain until it shuts off once every few weeks to keep the cells aware of their proper shutoff point.
its just that days ago my battery percentage still goes to 0 percent before it shuts off.. now after it prompts to recharge battery, about 15%, few minutes after it already shuts down.. maybe because i always drain the battery before i charge..
my app in my signature fixes the nexus battery if it dies early. need to be rooted though.
the "age" register in your battery needs to be adjusted to the proper value for your specific battery, which is done by a learn cycle. read the thread for details.
I know android has issues with correct battery calibration but I am wondering if the belief of people is right in that calibration improves battery life. I think calibration is supposed to let you see the true level of your battery at a particular time?
OR am I wrong?
You're right, it doesnt improve battery
Calibrating your battery (if done properly) brings up your battery life upto spec IMO... It's no myth.

The battery won't get better with the capacility or so, it will just use the full battery if it is calibrated right
Lol my english
I believe that with 10 or 20 charge system calibrates the battery too without erasing batterystats
as far as i know, battery calibration is really required for all devices that uses lithium ion batteries.
that is because, the usual notion that in order to preserve your battery life, you need to charge it only if its fully drained is only true for ni-cad and older rechargeable batteries, and is not true for lithium ion.
lithium ion needs to have a constant cell charge (cells are what makes up your battery inside) . meaning it would damage your battery if you drain it to 0%.
now this process of constantly keeping your battery charged, sometimes would confuse the battery's configuration (as lithium ion batteries actually have their own CPU boards inside them that acts as protection). now in order to correct that confusion, battery calibration is required once in 30days.
the calibration process is draining your battery till it turns itself off then charging to 100% while the device is turned off.
head over here for an explanation.

^^What he said!
Battery stats wipe them and your phone will restart the stats from zero .
Dont wipe battery stats and phone takes about two weeks to normalize battery stats ..
Wipe battery stats only required after flashing new rom .
