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...

Ok so this is what i noticed has been happening with my phone...
I wake up in the morning and i unplug my phone from charger at 100% battery life...
after about 1-2 hours of no use (outside of occasional check of time) and no programs running i notice that 25% of life has diminished...
i have turned 3g off and done most of the kaiser tweak settings that help with battery life. for the rest of teh day i can use the phone and battery life runs normally but it seems the first 25 to 30% drops real fast without use
is everyone experiencing this? is it normal?

The problem lies in your first sentence. "I wake up in the morning and unplug my battery." You are charging your battery too much thus killing it's battery life. I only charge my phone in the day while I'm at work. That way I can unhook it when it's fully charge. I would go on ebay and type in OEM battery Kaiser. You can pick one up for 15-30 dollars new.
From what I understand. Leaving your battery in the charger when it is fully charged should not damage the battery as long as its not there for an excessive amount of time but i might be wrong. Either way i have no way of charging the phone during the day as im on the go most of the time so this would mean even if i get a new battery it wont matter because it wile eventually do the same as i have only used this phone for about 3 or 4 months now. any other possibilities or solutions?
or should i just take it as it is and just buy a new battery maybe a bigger seido?
I thought Lithium ion batteries have overcharge protection. I charge mine overnight which I am sure a lot of others do also with no negative effects.

I do... Maybe I shouldn't?
I would hope it has Overcharge Protection!!!
With NiCad Batteries if you overcharged them you would kill the life of the batteries.
And while all batteries do this LiIon are least tolerant. If you overcharge a LiIon battery, that is without Overcharge protection, the LiIon Battery with BURST INTO FLAMES! Thus the problem with the Sony Batteries that caused all those Laptop battery recalls.

Thats total BS with lithium batteries.
To the OP: Try running down your battery completely once, until the phone switches off by itself, then recharge fully. If you never do it and always recharge before the battery is empty the battery's power meter can lose its calibration over time and display weird things.
If it doesn't help, and you can notice a drop in overall life time you might need a new battery.
I have the exact same "problem" with my Tytn II.
Is slows down evenly though. (So the first 5 % of battery vanishes in minutes basically while the last 5 % can last for an hour, when it's half full % will last somehwere in between these two extremes).
Personally I've just interpreted this as poor measuring done by the hardware and/or software. (Ie I don't think the battery performs better the less full it gets as the meter in Windows would have me think)

may seem a daft point but after draining the battery, dont charge with the phone turned back on. gives a fuller charge cos its not being used and makes it quicker to charge, lol

Hmm...I don't see how turning my phone off to charge would increase the charging rate dramatically. My phone in standby mode uses 1% every 2 hours.
depends highly on roms and especially on radios.
with a crappy rom, battery could drop as fast as 10% per hour.
with a decent rom, battery drops in standby mode at a rate about 2% per hour.

If the phone is on but on standby that barely changes a thing. If it's on, with display illuminated then yes it might take you an extra 20 minutes to charge.. no big deal either.
*UPDATE*
ok so i drained my battery last night completely(turned on navizon, tt7, and skyfire) which took me about at most 2 hours.
Put it in for a charge
woke up at 9 and checked to see and it was 100%
I have push mail set to update every hour and i also run pocket sportscenter autoupdates which updates every 10 to 15 minutes
I used the phone for 5 minutes of calls
5 minutes of web surfing
a few text messages
and the occasional time check
at 6:30 pm battery life was at an amazing 90%
i was thrilled.
i continued to surf the web heavily from 730 to 8
a few more text messages
at 9 battery was at 67%
so i gotta believe that draining the battery helped recalibrate it...
i guess every 2 or 3 months i got to drain it out and give a full charge
thanks for the help guys
really appreciate it
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,

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.
Click to expand...

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
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.
