Hello there,
I just got my HTC One XL from ebay and I have some questions.
How should I do the first charge? Should I use my new cellphone first and wait to the battery discharge in order to make a full charge of 7 hours?
Thank you!
If you bought it from eBay it's almost definitely not new, so the first charging process isn't super important. But, if you really want to you can plug it in until the led turns green, continue to charge for another hour, disconnect, turn it on and discharge it fully, charge fully again, then use as normal. Except for this first charge kind of situation it's generally not a good idea to discharge your phone fully, top-up charges are the suggested method.

It shouldn't matter too much with lipoly batteries, even when the phone says 0% it's still 3v which is only half discharged (safety margin around 2v before battery locks up and 4.2v which is 100%), there should be little concern with running a battery to the point it switches off as it would still have around 300 months shelf life.
There is no battery conditioning with lipoly only the way the android system determines the rate of discharge, it might for instance take 12 hours to get to 10% and then an hour to use up the last 10% as it's not figured out the discharge curve of the battery. Best thing to do is charge to 100% and allow it to run to switch off until it works out how fast or slow the battery rate is. Alot of the 'battery calibration' tools are worthless as they wipe the batterystats.bin which just allows android to determine this - giving odd readings (such as "my battery lasts twice as long to get to 50%" but then it is twice as fast from then on). useful if you have a new battery or it's out of whack but certainly dont need to do it regularly, contrary to a report by a so called android technician the batterystats.bin isnt wiped on reboot.
Sorry I go on a bit, I like to try and educate people on battery and charging methods to ensure they get the best out of them.. so as timaaa says, plug in and charge, use and discharge a few times and you'll get an accurate battery reading.

Regardless of whether the battery is only discharging to 3v when you "fully" discharge it, repeating that process too many times is harmful to the long term life of the battery. I found an amazing article written by a battery scientist which contained some fantastic information, the core advice: don't repeatedly discharge your battery, top-up charges are the best way. If I can find a link I'll post it for reference.

Why are you saying that? I bought it from: ebay.com/itm/111225894476?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
So, I have to plug it for make a full charge and then I have to use it, I will recharge it when it is 10% or 20% of charge?

The reason @timmaaa is saying that is because since our phone is so old (July 2012 release) it would be a bit weird to see a new phone there on ebay.
The first charge should be around 8 hours.Then you discharge once it hits 5% or so. Then charge it up full again, and let it die completely this time. and then charge full and don't worry about it again.
Now, more importantly, now that you have a new phone: WELCOME TO THE ONE XL FORUM! Hopefully we can see you around, trying out the various ROMs. A word of advice though: if you plan on trying these ROMs, I highly recommend you get root, boot unlock, and s-off all before you go and take the Sense 5 OTA that contains the latest (and non-unlockable) bootloader

Sorry, I am an old man with a family and i dont have a lot of time to search by myself.
First, thank you very much for your answers guys.
Second, is there a way to find out if the cellphone has been used? The phone looks like new tho.
Thank you guys and thanks for answering!

If there is a way to see it a smartphone has been used?....hmm that's a really good question. I would try checking the imei with HTC. See how long ago if the product has been used. That's all I can think of

It'd be highly unlikely for a phone that's over two years old now for there to be any new ones out in the marketplace at all. Even if it looks new, it's probably refurbished at best.

As pandasa said, you could try checking with HTC, short of that I don't have any ideas. If the phone performs well though it really doesn't matter if it isn't brand new, I only said that because if it isn't new I doesn't desperately need the usual first charge treatment.

Just hit the thanks button. It's pretty much the same thing. To check the imei: boot into the bootloader. So turn the device off, then hold PWR + VOL DOWN at the same time. The imei should be there

hi!
don't know if this is the right forum, but i think i'll give it a try
how can i calibrate the battery of my hd2? or is this not neccessary?
should i always discharge 'till the battery is nearly empty, or is this not a good idea and i should recharge at a certain battery-level the latest?
thanks very much for your help!
im getting v good battery usage and i do thid by full charge full drain 3 or 4 times and i tend to charge when gets to 10% hope this helps g

i think the hd2 general forum would have been more appropriate for this but i guess it won't hurt anyone if you posted here
there are many contrasting views about this and you will probably get confusing answers. i am not an expert but i'll try to brief you with some info i've got from my readings about lithium-ion batteries and my personal experience, of course.
so here we go:

1. discharge fully until the phone shuts down by itself
2. remove battery and wait ~1 minute
3. charge completely with the phone OFF until the green light is lit
4. remove battery and wait ~2 minutes

some recommend to do it every 3 to 6 month
here you'll find many that recommend you to do it after flashing a new radio rom.
from my own experience i tend to agree with this

i've read somewhere that lithium-ion batteries like being charged as often as possible and don't like being left without juice. this is the main reason some people don't want to even hear about the calibration procedure. but i think there is a big difference between complete discharging now-and-then and complete discharging as a habit.
i've never heard anybody recommend a precise low level limit when you should start to recharge.
there is no danger to overcharge though.

Hi,
I have a Samsung Omnia 7 unlocked but originally I bought it from T-mobile, and I was wondering if it's possible to remove the T-mobile splash screen from the start-up? Really annoying.
Thanks!
btw: i switched from iphone 4. never gonna go back.
afraid not. the carrier would of loaded it as part of the rom. give it time and you may find that you can flash a new rom on, but for now it's not possible.
Guess I'll have to live with it for now.
Thanks for the quick reply!

how often are you reseting your phone? I've only seen that screen about 3 times in 3 weeks.
I didn't reset the phone, just let the battery go off before recharging fully again. Just to make sure battery life will be perfect. Did this 3-4 times so far.

Not this again, some people myself included prefer to power cycle their batteries a few times. I don't care what anyone says but I always see an improvement after 2-3 charges. HD7 was crap for battery before I charged it a couple times.
May just be in my head...

New phones tend to "learn" a new battery. That may be what gave you the improvement.

You guys should be allowed to do whatever you want with your phones, but you should also know that there is absolutely no reason to cycle lithium-ion batteries.
question answered. the guy asked, i answered. no need to ask why or whatever.
mod, please just close thread. this debate goes on as bad as the android debates.

ORIGINAL POSTING, TRANSLATED FROM GERMAN< POORLY AT BEST>

Proceed as follows:
1. Turn your HTC Sensation ON continuously, and then loads 8 HOURS .
2. Get eight hours after the HTC Sensation of the drawer and then turn the power off . Now load another 1 hour .
3. Get the Sensation back of the drawer and turn it ON . Now wait a few minutes and then turn it back off . Finally, you still charge a 1 HOURS .
And voila, you now have the battery of the HTC Sensation longer trained to perform. You should make a clear difference and now you can even double as a battery to perform this method. You should start when the battery is already low on the Sensation and before sleeping. So you do not the daytime Sensation 8 hours long to miss.

"Its saying to manually set your batter stats, and yes it does work.
Charge to 100% take off the charger and power it down, when you boot back up you'll be anywhere from 80-95%, charge back up to 100% and then take off the charger, repeat this pattern till you can take your charger charger off (after a power down of course) and the battery readout on the phone stays at 100% for more then ten minutes, at this point just use the phone till it does completely, once it dies plug it in and charge it up to 100%."
_________________________
Also, please do the research about the bump charging, the forum i found this at, had NO mentioning of that, but I am glad people here knew about it before people started using it.
It does work, you will get better and longer battery life, but you will need to replace your battery sooner.
It is not as if you will need to replace it in a month, so weigh the pro's and con's, this still may be a very viable solution
Thank you XDA members for the input, I tried to update the OP to have the information needed to make the correct decision.
For more information on Bump Charging, Please Read
Quote from website above - ""To also help with Battery Life you can do these steps exactly: 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 Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well." - HTC Support's advice to an XDA Developer forum member.
This will reportedly increase your battery life two fold however in my test with the HTC Thunderbolt, I saw 14 hours usage which still isn't bad compared to the 9 hours I was previously obtaining"
An Article refereed to as the "truth about bump charging" that loops right back here to XDA A big thanks to byrong of XDA for his amazing thread.
*From my reading, the newer phones, like Sensation Evo3d, can handle the bump charge better then older, like the droid, etc....* (take that with a grain of salt......)
In my personal opinion, i think it is worth doing. The more i read about it, the more it seems like a good idea. I use my phone alot, and to get a full day with heavy usage is very important to me without plugging in on the ride home from work, etc.
can't make sense of it.
Indeed these instructions don't make much sense
after the phone is fullly charged,i delete /data/.battery-calibrated and then reboot
Its saying to manually set your batter stats, and yes it does work.
Charge to 100% take off the charger and power it down, when you boot back up you'll be anywhere from 80-95%, charge back up to 100% and then take off the charger, repeat this pattern till you can take your charger charger off (after a power down of course) and the battery readout on the phone stays at 100% for more then ten minutes, at this point just use the phone till it does completely, once it dies plug it in and charge it up to 100%.
It's called "bump charging". It's well documented to shorten battery life. Google it and make your own decision regarding using it.
Yeah bump charging will kill your battery
Sent from my HTC Sensation 4G using XDA Premium App
Yeah, the sensation has pretty good bump charge protection. I wouldn't recommend it, you'll get longer life for a while then it will ruin your battery.
definitely bump charging....do it at your own risk!
Thank you to all that have replied so far, i updated the OP so users can make a more informed decision.
I think i will try it on 1 of my sensations to see the difference. If i get 30%+ more life, as some of the people in the other forum claim, and i have to replace the battery in a year, I personally think that is a good choice.
All of this is upto you..
Remember, its your phone, what you do to it, is your choice, what happens to it based on those choices, is YOUR FAULT, good or bad. Dont try and play the blame game, good or bad.
The original post that i think that the OP is trying to explain was
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
Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.

Correct me if I'm wrong, but I understood it was a "suggestion" from some of the people in HTC tech support. I've contacted HTC tech support several times asking questions about the Sensation. Simple stuff they should know. "Does it use noise cancellation?" "Does it have Gorilla Glass?" "What are the holes on the back for?". I've been majorly disappointed. All I've ever gotten is "we don't know", "we did a internet search and this is what we found", "we tried one of our phones and you're right it does record in stereo.", etc. Never have they contacted real HTC techs and found the answer to my question. So, even if someone in HTC support said they tried this and it seemed to work that's not, in my view, an official endorsement from HTC.

I've done some Google searching and am still sticking to my belief that the original posted email was at best from HTC support, and not HTC engineering. As I mentioned I've received long emails from HTC support as well. I won't go into all the ugly details, but trust me they aren't tech smart. Battery bump charging, which is precisely what's described here, is widely known to provide temporary increases in storage capacity, but at a cost in battery life. But you can get batteries for as little as $10, so if you want to bump charge every day or two, have at it. Just be aware it could shorten the life of the battery and speed up the inevitable gradual loss of capacity.
I know some people say to fully charge-discharge-charge again the first time you use the device, others say not to do this, others say just fully discharge once a month to calibrate the battery. Well when I first got this phone, I charged it up before using it, then used it down pretty low but not a full discharge, then charged it and used it normally, and my battery life is pretty poor now. Was it bad to discharge it that much on first use? What do you guys do for the first few uses/charges?
You do nothing.
Just charge it and use it. Anything else is just a placebo.
There is no such thing as battery calibration. Battery stats may become inconsistent overtime, but a restart resets them and going down the full charge it becomes normal again. Just... use the thing as Rusty! said. :cyclops:
Thanks for the replies, that's good to hear. What about the fact that I used it down to single digits on my first use (after a charge)? Could this be harmful to it?

The biggest harm you should avoid is your battery getting molten hot.
No.
Thank you all for the replies....very good to know. After coming across a few articles that said anything too low isn't good for it, I was concerned that was doubly true for its first use. Glad to have it cleared up.

The G5 isn't THAT old, geez.
Anyway, my V20 was doing this, and it was just a ****ed up battery, misreporting it's percentages.
You can also try to do the battery stats cleaners if you are rooted, but I don't know if those even work anymore.
What I would recommend, is let the battery die, then charge it with a 900mah charger.(Something from an older phone) and let it sit without touching it.
Sometimes letting it charge with the slower chargers helps get it back to life

thanks. makes sense. I'll keep an eye on all three, see the differences.
The battery being kaput isn't exactly true I don't think. I have 3 different batteries and without fail at 15% it will tell me the battery is dead and it will then proceed to shut down. No bettery saver, just a black screen. Phone has been doing this since I got it. Stock rom or custom doesn't matter. Not sure if this is the right place to post, I have a H850.

Replace battery. Only sure way of isolating The issue
Phone shutting off at about 15-30% power without warning
This is the third phone I've had it was just replaced about 3 months ago I should say third replacement... Gets really hot messes up here in there... Recently I updated with the new 8.0 software... Now my battery cuts out at about 24% like clockwork so I replaced it with a new factory battery bought a T-Mobile for too much money... And it does the exact same thing... The bloody unit used to be able to do maps I could text and do other stuff at the same time and it would last you know for a while now if I do maps and a couple of emails or mean or text it's dead within an hour dot-dot-dot all since I've gotten that new 8.0 software

I'll second this. My main battery did start to swell a little besides the sudden shutdown at 15%. I also know that this swelling can eventually cause the fingerprint sensor to malfunction. Beware. Anyhow, I decided to use the "almost dead" battery to game for long hours while charging (PUBG). My healthy new battery was used for normal usage besides gaming. Hope this helps!
