Did you start using Sensation right away after opening it or charge it first?

So, I've had my sensation for a week, it was nearly perfect. But I wasn't sure that it was the best unit, cause battery was used fairly quick, GPS kinda weak, and a slightly washed out screen. I took the 14 day advantage I had at Walmart, and just today headed out there after work to grab the last unit they had! I called like 5 diff. walmarts but only that one had one unit.
Even the box was in such pristine condition, compared to the one I bought earlier, even though both were new. The first box had a date of 5/27. This new one has 6/3, so I'm hoping the June units might be better. Both Taiwanese. I haven't even opened my new Sensation yet, feel excited all over again
Anyways, to come to the point, how did you all start using you new phone, did you just take it out, turn it on, and use it? Or kept it off, charged it all the way, then use it? The reason I'm asking is cause the first one I had, I kept it off and charged it all the way. During that process, the phone got extremely hot towards the bottom, I mean hot like I've never ever seen in any phone before. And it pretty much stayed that way for atleast 2 hours straight. I'm thinking that I maybe messed up the battery up, cause too much heat can damage them. What do you guys think?
Edit: Another thing on my previous phone: the battery gauge was wacky. I would use if for hours and it would stay at 100. Then suddenly show like 85 or something.

usually I will leave it off and charge it fully before using it. This time I turned it on right away, let it drain then charged it fully while off. I've only had my sensation less than a week so really cant ccomment on battery life. When you first get a phone though battery life will be worse because you play with it tons when you first get it

Charged it before turning on & it never got hot

Yeah, mines seemed like a fluke, I've never had a phone do that before. This time, I'm thinking that I'll prolly turn it on before charging just to be safe.

My first two, I did. This one I used right away and today it's been unplugged for 11 hours and I'm still at 47%

I play with it until it fully dies, then I let it charge all the way; for the batteries sake. It last much longer that way.

I couldn't wait for it to charge completely.

I wasnt even out of the T-Mobile parking lot before I had my sim card in it and was messing with it lol.

Could you please tell us how your new phone is? I'll update my post when I check my box for the date but my battery does heat up and my power button is the slanted one.

Exactly....that's what most all manufactures recommend. I didn't notice it in the Sensation's manual, but I know I saw it in my G2X's manual.
For the last 5-6 devices I've had, I always run it dead from the box, then let it fully charge to 100%. As far as I can tell that really does help either calibrate the driver or condition the battery. I also do that pretty much every time its convenient.
I've never just charged it straight from the box.
I've always had great great battery life, under heavy use, for every phone I've had using that method.
I really don't know how important it is, but I know I've never had any of the battery issues that it seems many have with various devices.

Great advice, however I wanted to ask you that when you charged it back to 100% the first time, did you keep the phone off all the way? Also, did you perform any kind of a hard reset on it, and if you did, at what point?

I will surely report that info as well as panel info tomorrow after 7PM, as its late, and I havent opened the box yet. I was still trying to figure out the best way to start using the phone, as I didnt want to repeat the mistake I made last time.

No, I let it die...plug it back in, turn it on.
Some people do factory resets out of the box....I never have (out of the box)...
I get easily a full day, 14-16 hours, with consistent use. WiFi always on, gps on when needed, tons of web activity, light gaming, 100+ texts, dozen or so calls. That's pretty normal.
The Sensation seems to go from full to 90% in a hurry, but then really levels off. No idea why, but it's undeniable with mine. Also, this phone is by far the best I've ever owned when it comes to idle power consumption. I'll regularly leave it unplugged while asleep and it might go down 5% at most.
That's my experience.....hope it helps.

Hoggles, thx so much for your insight. So after reading quite a few pages on other forums, especially the IPhone ones, I think I'm gonna fire it up and drain it & then charge it fully while its off. Now the only thing to figure out is when to factory reset the phone, as soon as I first turn it on, or after it has fully charged? Also, when fully charged, is it best to unplug it and then start it, or start phone while plugged in, and then remove the power cable once it comes up?

I really don't think ya have to get that nit picky...as far as when or how to unplug.
Pretty simple and hard to go wrong....
Out of the box....use it til it shuts off on its own
Plug it in....
Turn it on if ya need to receive calls etc...
Let it charge to 100%...
You're Golden
Repeat whenever you have the time...once, twice a month works for me.

If somebody helped here, go back and hit the thanks button. It's a small gesture, but it lets the poster know you really liked it

I'm also use it out of the box until its battery drain and warning indication come out. Then I charge my battery.
I facing a weird condition during charging, where its goes up to 80 or 90% fast, but then to reach 100% very slow. It took 3.5 to 4 hours for my phone to reach 100%!!. I already use my phone for 15 days.

This is the "proper" way to condition a Li-Ion Battery. it's best for the battery life during every day use and into the long term. Ideally you should use it until it get's down to about 2-3% then charge fully, and repeat at least 2-3 more times. Your battery will thank you for it.
I had started to think that this tried and true method was NOT working on my sensation and then today, almost one week precisely after I'd gotten it I saw a huge, noticeable difference in battery life over the first 3-4 days.
Condition your batteries people! You and your phones will thank you for it!

I got the phone at Walmart the first day it came out and used it then charged it all the way.
Phone got very hot and I can not get it to last more than 6hrs on a charge no matter what I try.
(No GPS No WiFi No extra apps......you get the point)
Trying to return the phone to Walmart but they don't have any.
Something is definitely off her but I don't know if it's the phone or the battery.

[BIG ANSWER][MY GUIDE] Battery Life drain issue - solved

So i have decided to say something, and to write a little "MY GUIDE" :
First of all, this thread is due my AWESOME BATTERY LIFE
I'm running Insert Coin 3.4.1 with Bricked 1.4r1 Kernel.
I have done following steps :
0) First of all, you have to drain your phone dry (dead, till it powers down itself).Turn of fast boot (this is very important)
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
4) I wiped battery stats then when finishing those 1-3 steps.
5) Used phone regular.
6) For next 2 charging cycles you have to again discharge your phone untill it powers down itself
7) Charge it for 8 hours (i did it overnight)
Click to expand...
Click to collapse
After that 2 more full charging cycles you can charge your phone as much as you want and whenever you want. Charge it on every percent..
When you are charging your phone (after all 3 cycles), try to charge it when it drops under 30% and to charge it untill fully charged green light.
But i understand that sometimes you cant manage to charge it fully and when it is under 30%. Never mind. It is recommended but it is not required every time.
I'm trying to completely discharge and charge over 8 hours once per 1 or 2 weeks.
And after all this i have very good battery life.
With moderate use, my battery lasts over 24 hours (moderate use - lotof voice calls, lot of text messaging (SMS), checking on foursquare and little surfing over mobile network (HDSPA), alot of surfing over home WiFi.
In standby it cant be compared to anything i have heard here : I have 1% per 3 hours drain in stanby.. maybe even more hours, i cant properly determine but overnight when it is not charging i loose not more than 4-5 %).
My setup on phone is following :
1. Manual setup of brightness (im thinking of getting baadnewz auto brightness tweak)
2. All options in sound settings ( increase in pocket mode, flip over for speakerphone, quiet ring on pickup etc) are disabled.
3. Network is on GSM only. When i need HDSPA i change it manualy.
4. Auto sync is off.
5. Vibrate feedback and typing vibration is ON (i cant live without it ).
6. Dont have any battery saving applcation (juice defender, watchdog )
7. I dont have any mA monitor . Im fine without looking at wrong values monitored . I just have BattStatts (percentage shower).
Click to expand...
Click to collapse
I hope you like this, and i hope this will help to some one here.
After all this time on this forum (over year and a half), a lot of people here helped me a lot with my problems with my previous device (HD2) and with my current device (Sensation), so i was in need to try to help other people with major problem (battery).
If you want, put this thread sticky, move it wherever you like, if it is helpfull.
Best regards folks.
Laynee1
p.s. If this helped in any way, or you find this post(guide) useful, don't be lazy to click thanks button I thank to you all for your support

Thanks for the info!
I just flashed Faux 0.2.4b kernel on my ARHD 4.1.5, gonna try this whenever I have enough time

Would appreciate thanks button hit
And , yes, try it.. and report results pelease
For example.. I charged my phone today, took it of charger 10am..
With moderate use i have 98 percents now.. It is awsome

That's called bump charging. It may increase short term battery life, but depletes long term battery life. HTC recommended you do this ONCE every couple of months.
Plus our batteries are lithium ion, so doing full charge/discharge cycles will practically have no effect. You could do it just to calibrate it wight the phone, so as the phone "knows" what's 100% & 0%. But other than that, fully discharging these batteries could harm them. These batteries like partial discharge. So charging them when they get to around say, 30% is more convenient for them.
Just thought I'd let you know

I didnt said to repeat this every day or week..
I said you should have 2 full charge discharge only once after u done 1st couple of steps..
Full charge and discharge once per 2 weeks will, in no way, harm our phones..
And i said
When you are charging your phone (after all 3 cycles), try to charge it when it drops under 30% and to charge it untill fully charged green light.

I have done steps from above, and i have great battery life.. short and long..
I know our batteries are lithium ion, and i know a bit about them (im finishing Electrical engeneering College here in Serbia (most difficult ever ))..
So
To recap..
This method CANT harm your battery or device.. It can only help your battery life.. Try it.. See it yourself

Thank you for your guide.

Woah, take it easy my Serbian friend. All that I'm doing, is stating the facts & trying to help you understand that what you hear about charge/discharge cycles are just carryovers from previous batteries where it was good to be do several full drain/recharge cycles.
Here's a perfectly clear explanation of the differences coming from experts: http://androidforums.com/incredible-tips-tricks/69534-battery-charging-myths.html
And a more detailed one:
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
What you experienced is bump charging, like I said, it may increase short term battery life, but WILL decrease its long term usability. So come on, this is a community, we learn from one another

@mzmo :
Mate.. You got me wrong. I appreciate your post in this thread . I find it useful. Ofcourse we learn from each other.
The facts ive put in OP thread are facts from my phone directly . First steps of guide was in mail HTC has responded to me.
So, all in all, thanks for your posts ,and for your future posts.. I find them all like big contribute to XDA community.. After all, i made this thread due to that
Cheers mate

Which bricked kernel version is better for insertcoin 3.4.3, v1.4 or v1.5
Thx

Thanks for the info.. very helpful...... i will try it out frm today. i have a huge battery drain
using ARHD 4.1.7 with faux latest kernel

[Q] How to increase battery life?

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?

Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn

ahh ok thanks guys ill do what you guys said and see if it helps

you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.

no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Download Gemini from the play store and manage the autorun for apps. That's what I do and it saves quite a bit of battery

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.

If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.

Help getting battery to charge to 100%

Hi There. I started having trouble with battery usage. Some services were using SO much power...battery would last an hour or two. It had been a good while, so I went ahead and wiped the phone and flashed a new rom. I was on CM10, now I'm on SlimBean 3.1.0 (also CM10).
I have a few batteries, and just replaced a third party one with actual an Samsung. Using new or old battery, they charge to 75% and stop.
I'm pretty sure they're charging all the way..once I start using them, it'll stay around 70% for a WHILE before droping below that.
I'm guessing there is some combination of draining/charging/resetting stats, but I have not found it yet. I tried resetting stats when the battery was full (at least.. around 75% and not increasing). Maybe I should drain it and then reset? I'll try that next...
Has anyone been through this with a Blaze that can offer some clues?

Craaaaap. I thought I had moved out of the dev forum. I'm retarded. Thanks for pointing that out.

Try pulling the battery, sim, and sdcard.
Let phone sit for about 5 minutes.
Pick up phone and hold the power and volume buttons for about 30 seconds.
Place phone down for another 5 minutes.
Put sim, sdcard, and battery back in phone.
Charge for about 30 minutes to an hour.
Turn phone on and let charge completely.
It's best to do this with a battery that is less than 50%.
Don't allow your battery to die completely if you can avoid it.
This trick also helps with laptop batteries.
NEVER, drop your phone in the toilet no matter how pissed you are at it...
Good luck, hope this helps, and next time make sure you are in the right section please.

Thanks. I'll try this.
Ugh...embarrassed. Will do.

[Q] Battery Problens!!

Ive had my htc one x for maybe 5-6 months which is almost the longest ive ever been on one phone and i love(d) it, but its always been doing something very strange and aggravating that seems to be getting worse. Battery drain has always been a problem for me with this phone but ehh i can deal with it, but once my phone gets down to about 14% which is does often because of the draining it starts acting real funny with its power and sometimes goes from 14 down to 5 in an instant literally out of no where and as soon as i plug up itll go right back to 13, or itll shut down entirely at 14% but i can just cut it back on, or itll shut down in the middle of me doing something and i have to charge it for about 5-10 minutes before itll even come back on. The latter happened last night btw. No matter what combination of roms/kernels i try this always seems to be a problem. I really cant deal with this anymore and its to the point where i wanna throw my phone into a wall and just buy another one, which im seriously thinking about doing at this point. If such thing has happened to anyone before or you have insight on this can you please help before i just give up hope completely.

What you have described is normal for our device. Remember that the battery percentage is just an estimate of your actual charge. In addition, you find your phone shutting off around the lower percentages as a result of the device attempting to prevent damage to the battery. That is what the HOXl was designed to do.

Do you allow full charges after these "forced shutdowns" occur? This should cause your battery to recalibrate.

The battery behavior on this phone has been interesting. I have the battery last over two weeks on airplane mode and I've had the battery last just a couple of hours with just a stock setup. There are so many factors that play into this. I work in an area with very little to no signal reception and my battery life goes crazy and the phone can get really hot while I'm there so I've seen the best and worst.
What I do to counteract this bad behavior:
1. Charge prior to 40% (I've had the phone go from 40% to zero instantly before)
2. Consider your signal reception and either try out different radios or use airplane mode to reduce erratic battery drain
3. Install a 3rd party app like batterycalibration (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en) and use that when things get hairy (I calibrate every two weeks or so and that does the trick for me.
My phone has been like this since I pulled it out of the box. With a little management, it is just fine. You have seen it before but I'll say it again, you have to get through a few charge cycles when flashing a new Rom to get back to normal.
Hope this helps. It works for me and I work in a cell phone reception hell.

Ive had my htc one x for maybe 5-6 months which is almost the longest ive ever been on one phone and i love(d) it, but its always been doing something very strange and aggravating that seems to be getting worse. Battery drain has always been a problem for me with this phone but ehh i can deal with it, but once my phone gets down to about 14% which is does often because of the draining it starts acting real funny with its power and sometimes goes from 14 down to 5 in an instant literally out of no where and as soon as i plug up itll go right back to 13, or itll shut down entirely at 14% but i can just cut it back on, or itll shut down in the middle of me doing something and i have to charge it for about 5-10 minutes before itll even come back on. The latter happened last night btw. No matter what combination of roms/kernels i try this always seems to be a problem. I really cant deal with this anymore and its to the point where i wanna throw my phone into a wall and just buy another one, which im seriously thinking about doing at this point. If such thing has happened to anyone before or you have insight on this can you please help before i just give up hope completely.

When a new ROM or kernel is flashed you need to let battery settle for at least 48hrs before you get super worried about battery. If possible during that time let device fully discharge then charge up to 100. Please use a battery monitoring app and then see what's causing the issues. With proper config hoxl will get good battery life. There is always the chance its hardware issue but doubtful as battery prolly would of completely failed by now. Also check your screen brightness settings. Hope this helps

Ive done all three methods youve mentioned before and still same thing. Also im on 3/4 bars with lte 90% of the time so no reception issues here. And with my current setup ive been running it for about 2 weeks.

Ive always let the rom settle in and i constantly maintain the brightness on around mid level (mirror screen protector so i cant go too low) but its not just one rom or a few, its with every rom i flash ad that consists of most roms available for this device

The battery behaviour you described is completely normal if you understand how a battery of this type works, and if you understand how the software (especially the display of battery percentage) works in conjunction with it.

So youre telling me having the phone get to 22% and instantly drop to zero and power down is normal? Makes no sense at all. Also i cant get it to charge too 100% for anything. So if theres no fix to this, anybody want a one x with a troublesome battery?

What I'm saying is the battery percentage displayed by the software is never exact, it's only an estimate based on the voltage level of your battery. Your battery sounds like its long term life (capacity) has been decreased over time and possibly bad treatment (allowing the device to discharge too much too many times).

Depends on what you define as "normal". Such behavior is certainly not unheard of (although you particular collection of symptoms may point to a more serious issue, which I'll get to later). Couple things you have to remember: the battery meter is far from accurate. Being off by 10% or more is not unusual (completely normal). So jumping from 5 to 13% as you mentioned is not out of the question. The battery voltage is not actually jumping around, just the % battery number that the phone is assigning to various voltage readings. Reading errors happen, and if a jump is noticed, its just the meter correcting itself.
Which brings us to the other point that should be kept in mind: the battery % is not a "real" measurement. Its just a number assigned to various voltages to give the average person a sense of how much battery is left. Its a completely fabricated and artificial measure that just gives some relative sense of when a user should charge their battery. Phone makers just decided to use a system that average people would understand, like the fuel gauge on a car. Zero doesn't really mean zero (or anywhere close), but reporting in voltages would make no sense for most folks. Also, as we all well know, just because (for example) it took you 12 hours to drain the phone to 50%, does not necessarily mean the phone will last another 12 hours to drain the remaining 50%. It all depends on what you are doing with the phone during that time. Which leaves the question: What does the % battery really mean? Really, not a heck of a lot.
On the other hand, the battery failing to charge to 100% is troublesome, as is the apparent frequency of the meter drops and the fact that the issue remains after various ROM flashes. Leads me to believe there may be some hardware issue going on.
The short answer: IMO while some of the individual symptoms are not unusual, the seeming frequency (you haven't exactly quantified this, but it seems relative frequent just based on your descriptions) may suggest a larger issue, but its not certain.

Thanks it explained a lot but it happened again today, went to the store with ~36% on the meter and walked out, haven't touched it at all, phone was completely dead. Tried to charge and it went to 6% and stopped charging, all signs showed it was charging but it was stuck on 6. Then it started climbing again and reached about 16% and actually started losing charge while on the charger. Switched over to my portable battery charger i just got and it held the charge at about 5% for ~30 minutes, which is what it was when i plugged it in and started to charge, then it stopped againand during the whole process the phone was getting very hot. Yea im getting a new phone :/
