Morning all , the past 3 days I have been noticing that my Excalibur just shuts down and won't restart unless I plug it into a power source and power on.
Has this happened to anyone else?

Sounds like you need a new battery
Thanks man - any specific one you can reccomend? Reason I am asking is cause I have seen people post different battery makes, models etc..
URL Links would be appreciated.
If that's all i have to do - it's an easy fix for a 200.00 phone!
Thank you.

Take a look on ebay i use a 1150mAh but go for the 2200mAh and you'll be impressed, if you do a search for battery on here you will see what people recomend.
If you are already on a spare phone, try giving your excalibur a full charge, and turn it off. Allow the battery to drain out completely. And if possible repeat this once or twice more. Complete power drain will improve the average life span, and can be done atleast every 3 months on all normal devices, so as to increase the lifespan

Nice, that is good to know... Never really knew that... Plus also I wanted to ask... is it bad to charge your phone everyday when it is like at 50% of battery life...
Nice question.
Think about a tank. You fill it with wet cement. And u take the wet cement for use slowly away. Almost as soon as the tank is 20-30 percent empty, the cement is filled gently again, so as not to shakeup the cement at the bottom. After a while the cement at the bottom hardens, and u cant get it out for use. And same happens with the total amount of cement u could pour in. Earlier if u needed 25 pots to fill it up, now it gets filled with 10 pots or so.
Now think about the battery with multiple cells arranged inside. You fill it up. Then u use up the top 3-4 rows of small cells, and immediately fill those cells right back. This keeps on happening. What happens is that, the cells at the lower rows are never emptied, and the charge remains static there forever, and after a while the cells just freeze up. Meaning, it is not possible anymore to fill them up, or to use up the containing charge. So when u start filling up, the battery says charged fully pretty soon, cos there are less cells to fill up, and good enough, the charge falls dead soon too.
The above analogy was true on the days on Nickel Cadmium batteries. Now a days with Lithium polymer batteries, what they say is the charge is not stationary at one particular site and keeps on revolving all inside, so there is no question of dead cells arising. Well theoretically yes, but practically what the geeks suggest is to charge the battery only after completely draining it. Well, not really feasible with our busy lifestyles, as we cannot start a day taking the 30 percent battery with us.
This is what I have been doing, Charge it up as much as I need it during the weekdays. During weekends, when I am near a powersource, I keep it until it drains as much as empty. And once every 2-3 months, I try to make it empty fullest.
So I guess, it is more of a personal choice of ease also. Though the current dictum is that, charging the batteries at whatever level is ok, experience has shown many users to allow complete drain occasionally
thanks CC.. i will try that..give it a full die out and charge it up again.
If that doesn't work i'll get a new battery.
Appreciate it!
since you seem knowledgeable on batteries... i also wanted to ask how long do the batteries typically remain "usable" to a decent amount...
Aah not at all knowledgable. All I know is my own personal experiences plus data from a million sites that I read.
The typical duration and lifespan of a battery depends mainly on the capacity first of all, the more milliamps u have, the long lasting a battery is. Also the average life depends a lot of the number of charge cycles. Means, if u r a light user, u wnt have to charge it every now and then, the batt will slowly discharge, and then u charge it once or twice in a week.
For heavy users,at times myself included, I put it on charer more than once in a day. There the total number of chare cycles that the battery is alloted gets used up early, and the battery dies early.
A third factor is the amount of load we give to the OS. Not just playing heavy games or apps, but making calls in low reception areas as well as placing our hands over the antenna portion of the celphone while making calls, increase the load, and cause the battery to drain faster

i have the same problem with my phone just shutting off after about an hour on, only turning back on when plugged into a power source.
i've got a 2200ma battery on the way and i can't effing wait for it to get here.... i really hope it solves the problem cuz i already reinstalled the kavana rom thinking it was a software bug. reinstalling gave it a breath of fresh air nonetheless, while its on. lol

Hey man - please reply on this post when you get the battery replacement to let us know if that helped solve the issue. If not i'll have to jump in the market for a new smartphone.
Theres nothing worse than being on a business call and you loose the call - and your phone usability with no power source around.
Please keep us posted.

Yah you should do that... let it die 3 times and charge it fully, also do this about once every 2 weeks I would recommend okay... or whenever you can...

Hi all, first post.
My Desire is new to me so I'm playing with it constantly, which is obviously killing the already marginal battery rather quickly. On previous 'regular' phones I've always tried to run the battery as low as possible before doing a full recharge, but this isn't possible at the minute as I find myself running low mid-afternoon, so need a top up to make sure I get home without it going flat.
Will this harm the battery in any way? I know battery tech has come a long way in recent years, but I don't want to kill it prematurely by just putting an extra 20-30% in it now and then.
Thanks in advance,
Andy.
Not good dude, the desire use a li-on battery so a deep discharge is one if the worst things you can do to it. Jump into google and have a read of the wikipedia article on it

Some advice I can shed on this is having Wifi on all the time, (by all the time you mean at least 24/7), that could be a strong point why your battery life is low. Another thing is the number of apps that require data being pulled running in the background
1. Having Wifi on for the time you state is bad if you don't have a signal. Reason why is that since there is no signal for your Wifi to obtain it will continue to search and fail, search and fail which actually drains some good amount of battery being forced to repeat such a task unlike when having a steady signal it's usage becomes minimal
2. High number of data pulling apps also works the same except then have the option to change the time they pull data which can be usually found under settings/options tab
Try these out and let us know how it goes =]

Hmmmmm
I barely noticed that you are running a custom rom. After flashing the new rom did you wipe battery stats? If not, that can actually affect battery life as all roms run differently and different data is applied to the battery stat
There are two ways to go about wiping the stats. You can boot into recovery and Wipe Dalvik Cache under the advanced settings or you can download Battery Calibration from the marketplace which in my experience is a lot easier
Battery Calibration
The instructions are inside the app on how to implement the process
I had this rom for a while but when I flashed it, I did not wipe data or anything. I decided to wipe data to give it a try and reflashed it. I charged it completely and calibrated it. I am in the process of running the battery until it dies so I can recharge it to complete the calibration process.

DO NOT drain the battery until it dies!!! Just down to 15-20%, then charge to full, repeat a couple times. Over-discharge is not good for Li ion batteries.
People on here keep recommending it, or saying they do it. Its NOT a good idea, and proliferating this bad advice needs to stop. Draining the battery to dead is bad for the life of the battery. Also over-discharge can possibly render the battery unable to take a charge, requiring you to buy a new battery. It doesn't happen often, but its happened to a few different people on this phone, and other phones as well.

You seem to know a lot so i'm gonna ask ya redpoint. People say there is a built in safety zone so even when the battery is reporting as 0 it really isn't. The batteries do not allow themselves to get below a certain threshold for the reason you are explaining. Is this not true? Lots of people who know nothing of xda or cell phones in general let there phone run the whole way out for whatever reason. I would think that cell/battery manufacturers would take that into consideration.
the reason people used to tell you to drain the battery complete was based on an older battery tech that has what you would call a "memory" it needs to "memorize" it's lowest and highest point in order to calibrate the battery. Li-ions do not need that. They actually keep track of your charge cycles.
suppose it can handle 1000 cycles. on the first day, you used up 75% of your battery and put it on the charger to max. then the next day you use another 75% and do the same thing. at this point what actually happens is that the battery will count this as 1.5 cycles rather than 2 cycles. But redpoint is right.
Do NOT drain the battery completely when it's a Li-ion battery. it's old advice for old tech battery that is legit for that type of battery but not Li-ion batteries.
To calibrate your battery, you just use your phone normally. It will figure out where it is supposed to be as you use and charge it over the course of a few days.
better battery life

It is true that there is a built in 'safety zone' so that the battery does not drain completely to zero.
However, it is also true that this 'safety zone' can and HAS failed for some users (including some who are on these forums)
With the way that Li-Ion batteries work, and 'calibrate', there is no added benefit to draining it completely to zero. If there is no benefit, then the risk is not worth it.

These ideas ran through my mind reading your post:
I. You might want to calibrate your battery. I've run into many instruction how to do this (just google the keywords: Desire Z calibrate battery), but basically the ones that do NOT require you to drain your battery to zero first, came down to this:
0. Turn Fastboot OFF!
1. Power on your Desire then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Many people seem to have greatly increased their battery life just by following those simple steps. I am currently in the process of trying it myself, but will probably need some hours before I can verify if the overall life has significantly increased.
II. You might want to install an App like "Watchdog lite" for a longterm check if you have any apps or processes, that work as a battery eater in the background.
III. if the above tips should fail, you might want to upgrade your radio and maybe also align the radio library (RIL), to match it best with your radio and ROM. But do a lot of reading and research before actually performing that task, since this is nothing for beginners and might even make things worse. This thread might be a good point to start your research.
hope that helps,

Hey I've read on other forums about these battery calibration apps and whatnot, just want to know if anyone has used them and know if they really do work? The wife and I both have the Dinc2 and i loaded andybonestock on both of our phones.. i use my phone like crazy and she barely uses hers. i put drellis's 21 on and UV 50 and within 15 min off the charger i'm down at most to 98 battery and she's already down to 90. her battery drains rediculously faster than mine and they're both the same exact rom's and kernel specs. Will these app's actually work or is there a real/better way to get hers working better?
Use battery calibration from the market and follow the instructions to a T. Her battery could also be defective. Try the calibration first though.
that's what i'm trying to do. I have it charging right now, at 84% then im going to run it.. just wanted to know if there was any proof it worked or any other option
I left my inc2 get charge to 100% and then use the battery calibration,i notice that my battery goes down from 100% to 97% in just 5second,the battery life is good after goes to 97%,but im not sure why goes down to 97% that fast.

Just a heads up, that is normal, your battery will never stay at 100% it doesn't charge to 100% unless you bump charge it (and that is bad for your actual battery). Having it drop anywhere from 97% to 92% is common, after that you will notice a substantial slowdown in battery drain unless you are heavily using the phone.
I added a picture of my battery life as an example of the length I am getting from the ICS Rom I'm currently using. I have my phone oc'd to 1.4ghz and uv -25 across the board. This screenshot was taken after a day full of phone calls ranging between 3 minutes and 20 minutes, moderate browser usage, moderate facebook usage and lots of texting.
Ya I knew it wouldn't stay at 100 at all but like how mine would be at 97 after 15min and hers at 90.. it just didn't add up.. she rarely used her phone and only had about 6 hours of charge, while my battery with excessive use had enough battery to last me about 16 hours. I reset battery stats and then bump charged her phone. Now its fine

glad you figured it out.
careful on bump charging, it decreases the life of the battery itself everytime you do it.
I personally don't use the apps. I've had the best luck with charging to 100%, power off and charge till green light, unplug and do one more time, boot to recovery, wipe battery, power up and unplug. That's just me though.

Charging to 100% and then powering off and charging again IS bump charging, that is bad for your battery itself, it takes away life on the actual battery everytime you do it. I said this above. You may be getting an extra half hour to an hour out of your batterys life but you are decreasing the amount of times it can actually hold a charge each time you do that, therefore ruining your battery for a tiny bit of extra battery life per charge.

I'm quite aware of what it IS. I also didn't say I do it every charge. I also know that some say its not good. I also know some say smoking can kill you. I also know I've done it on other devices with no problems. And I also didn't say for anyone to do it. I only said what I do and what has worked for me.

The smoking analogy doesn't really relate, smoking can kill you but doesn't always, bump charging for a fact decreased the longevity of your battery hence shortens the time before it does not hold a charge anymore and you have to buy a new one. I made a factual comment, I did not need a condesending response.

Have you tried loading a stock ROM on there just to be sure it's not software causing harm to your battery? Not sure if your provider will warranty your battery if it is indeed your battery.
Good luck!
Hi, thanks for your response
It actually is stock rom, sorry forgot to mention it. It is rooted, but I never replaced the rom, just put in CWM recovery. I just moved from rogers to virgin mobile last night, just changed sim card. But the multiple reboots killed a maybe already weak battery?
Thanks

You should download and install better battery stats, it may help you find out if its being kept awake and draining quickly that way

Thanks for your response, necrowakker.
I guess that I forgot to mention as well that the phone was shut off during a recharge, and upon powering up, it still it complaining to plug it into a wall charger.
Like it was never plugged in.

When you rooted your phone was the kernel changed? .. I've had experience with some custom kernels not reading the battery correctly when off, and only after switching it on it still States its low til a little while later it actually looks like its charging .. ( like the battery level goes up over time) while being off the charger.
If thats not the case, try charging your phone again, but while its on after you know its definitely discharged and not just a ROM memory issue. If you turn it off to keep from getting calls during the night switch on airplane mode to keep that from happening. And check if your battery does on fact charge correctly. ...
After 3 full charges and discharges your battery still gives you bother. Then you can either look into what process it was when you rooted,
if it did change anything more than just giving you more access, or see about a hardware replacement, if it is under warranty, and you can take the flash counter back down to zero (if it counted up) and unroot it.
Also using unsupported chargers over the recommended charge rate for your phone, could have done it damage but that's a long shot with today's safety measures on phones.
Edit:
Don't forget to install better battery stats too, just for checking and reporting. Stable ROMs should be able to handle over 300 hours up time before needing a reboot. So using airplane mode should not bother your phone too much
Sent from my Pengus77 powered LG-P990 using xda app-developers app
Thanks for all that info.
The phone has been rooted for at least 6 months now. It has been running very good until this morning. No kernel was changed for the rooting. I just wanted titanium backup to work.
I am still presuming that maybe the battery was weak, and when I was changing out the sim card of the service providers, I did reboot about 15 - 20 times to try to get all the services running, maybe that was enough to kill a battery.
Heeter
I've don't some silly **** with powering and charging and pulling batteries for every reason, I can't see Samsung giving you a bad battery if its worked fine for 6 months, you'd probably know within the first 6 weeks if it was faulty. ...
It may easily be a software memory issue with the battery that's confused it. If you are using cwm as a recovery it may have the erase battery stats option on it, if so give it go,
charge your battery to 100, allow it to drop to zero, or til it shuts down, plug in, power it on allow to boot, and leave to charge to 100,
once that full discharge and recharge is done, your battery has its full stats. If it gives you hassle after this point, think about buying a registered Samsung replacement for your phone.
