Though LiPo batteries don't like to be overly discharged, I'd stop short of saying that this is detrimental to your battery. LiPo batteries shouldn't be left at low voltage (dead) for long periods of time, but discharging it entirely and then recharging it is well within the designed specs of the battery. It's more the fact that they lose charge over time, and therefore leaving them dead which is considered their minimum safe voltage, will then allow them to drain further themselves over time to a point where it's detrimental. I suppose, though, a battery drained to 0% every single time is more likely to have a shorter life than a battery discharged only to 20% before recharging.

The Android system does calibrate the battery life, which is more of what you'd be doing, but you aren't going to get more battery life out of a battery by discharging it entirely, then charging it fully, it just doesn't work like that. LiPo batteries don't have issues with memory or needing to be discharged or charged to a certain point for optimum performance.

I 100% attribute bad battery life when you first get a phone to simply being you pulling it out and turning it on more than you normally would. It's nearly impossible, and damn near subconscious, but when you get a new toy, you're obviously going to pull it out to look at it, play with it, load every different app it has, etc, as well as doing the same when you show it to people. I think even if you think you didn't play with it a lot when you first got it, you likely still do. But that's just my opinion.

The dtremental effect will be minute, accepted, but there is certainly nothing to gain. That's what I wanted to make clear.

There is a lot of guesses portrayed as fact on here these days, as well as conclusions drawn from dubious experience with no control or comparisons. Just trying to combat this misinformation.

It flys in the face of the laws of physics??!!!??? What the hell are you talking about? I'm talking about my battery life getting better and better cause of draining it and recharging it not the gravity of the moon or Einstein theories, relax.

[HTC One X] barondebxl:
That's fascinating..... I wonder where that battery calibration thing started in the first place, I guess someone made that up just to mess with people right?
[HTC One X] AJerman:
For batteries that needed calibration? And as I said, a lot of people confuse calibrating the battery meter in the OS with calibrating the battery itself.

[HTC One X] tkolev:
To all of you who say that using up your battery shortens it's life, I have just one thing to say: the phone will never let you fully discharge the battery. Approx. 3.5V at which the phone turns off is far from the voltage of fully discharging (and potentially damaging) the battery.
[HTC One X] AJerman:
As I said, this has nothing to do with calibrating the battery, and everything to do with calibrating the battery meter in the OS, which, by the way, will never be off by HOURS, maybe by a couple of minutes. This only needs to be done once every however many cycles, that site says 30, but I wouldn't even bother doing it more than once every couple of months at the most as you likely won't see any real gain from doing so, and it IS theoretically bad to overly discharge your phone. Doing it once in a while won't damage anything, but doing it every cycle, or every day for a week or anything like that is excessive, unnecessary, and, as farnsbarns mentioned, can wear on your battery.

Battery meter calibration has been discussed on this message board countless times, and every time it's proven to be nearly pointless in real tests.

Edit: This is not to mention that I think a lot of batteries/phones have charging circuits built into them that allows them to properly check the battery level itself, meaning calibration of the OS isn't necessary. I could be wrong on this, but I'm pretty sure I've read about this before.
[HTC One X] barondebxl:
Nothing to do with battery calibration? Have you read the article? If you want accurates readings, you want your battery life to improve, you probably want to calibrate your battery. I've had the one x for almost two weeks and my phone doesn't jump from 50% to 42% randomly anymore cause I've calibrated the battery. If you want more reading : http://www.themobileindian.com/news/5547_How-to-calibrate-smartphone-battery

No one here said that it is something you need to do everyday, but when you get your phone I suggest doing it. Then once it's calibrated do it once a week or every other week.
[HTC One X] barondebxl:
they do have charging circuits I just read it, still you want accurate readings. Even my iPad sometimes displays wrong battery percentage when I don't let it discharge. Sometimes I charge it when it's at like 28% for example, let it fully charge but then it drains weirdly.
[HTC One X] AJerman:
You are failing to listen to what I'm saying. I've read the article, and many others like it. There is no such thing as calibrating Lithium batteries, and it's a common misconception, so I have full faith that you can find countless web pages telling you you can. It comes from the old mindset of batteries that did need certain charge cycles (full discharge, full charge, etc) to maintain life.

Again, the only thing you calibrate when you run the battery all the way down is the OS's battery meter. Android shuts itself down automatically when battery voltage hits a level that is considered empty or dead, regardless of what the battery meter says, so that calibration gives you no more life out of your battery at all.

However, I think we all run down our phones to the point where they auto shutdown more than frequently enough to consider the battery meter calibrated very close at any given time. Battery meter calibration is more an issue on systems that stay plugged in frequently and don't often get discharged, this is usually with laptops used as a desktop replacement, not phones.

We aren't trying to be mean or anything, just trying to squash the continued misconception that calibrating the battery is possible or has any effect.
[HTC One X] barondebxl:
But that's simply isn't true. When I had my sensation, didn't know anything about calibration or rRoms or anything was a noob. Now for a couple of times I remember my battery diying on me when I could have sworn I had some battery life left. Waited about 10 min then turned the phone back on with like 5%-7% left. What is that? I've had my sensation for two months before I got rid of it so it was fairly new.
[HTC One X] AJerman:
The battery meter not being calibrated properly? After it did that and you fully charged it again, I bet it didn't turn off at that high of a percent the next time. That's what I mean about battery meter calibration vs Android shutting down the phone when the voltage reaches a certain point. I bet when you turned it back on and still had 5-7%, it probably still turned itself right back off after it finished booting, right?
[HTC One X] barondebxl:
Not right after but 5% is nothing so it didn't stay on for 10 min. Can't remember exactly but still.
[HTC One X] farnsbarns:
YOUR BATTERY IS NOT GETTING BETTER BECAUSE YOU'RE DRAINING IT, IT'S GETTING BETTER BECAUSE THAT'S WHAT NEW LI-PO BATTERIES DO. THAT'S CHEMISTRY AND PHYSICS.

So, you spout a load of nonsense and then when you are corrected you tell me to get out of my basement. You can't have your cake and eat it. Either knowing what you're talking about is important or it isn't. In your case it isn't important but you love to pretend you know what your talking about, yeah. There's no point in this discussion because your unable to accept that you're wrong.
[HTC One X] spekesel:
So we agree (cept the OP) that this is pointless misinformation right?
[HTC One X] lostunsunghero:
sorry but this totally contradicts my findings. The one x has amazing battery life right out the box. Today i i got about 5 hours total screen time from one charge to full. I was streaming video for about 3 of those hours (both euro 2012 games that were on today (only turning off the stream off at half time in both games and the hour in between the 2 games).

For the remaining period i was making calls, sending texts, spent about half an hour playing draw something, recorded a 5 minute video on full HD and stereo with the flashlight on and watched a couple of youtube videos in HD.

Wifi-on (but not connected), the stream was all from my HSDPA connection, screen brightness set to auto (but changed it to the lowest when it hit 35% battery. Stock ROM (vodafone UK), not rooted.

Results:

12 hours 50 minutes total time

~5 hours screen time

(everything else was around 2-8%) apart from mx player which was at 13% and the screen was 72%

remaining battery is still at 11%

Absolutley fantastic
[HTC One X] farnsbarns:
Yep, and enough has been said to ensure that anyone looking for real information will, at the very least, take the OP with a large pinch of salt.
[HTC One X] stezo2k:
Why do I feel like i'm the only one who gets poor battery? I'd be so happy with 5 hours screen on time, i'm lucky to get 2.5 really and I don't really game and watch much HD content

Can't wait to get a battery case
[HTC One X] TommUK:
Your battery life didn't get better due to draining it and recharging it, Li-po batteries don't retain memory and what you did will have no impact. Its not a Ni-Cad battery.

And, dude when someone says physics you think only of gravity or einstein?

How about the Electrons inside the battery for instance?

You're talking about the app that wipe the battery stats. That's not what I'm talking about.
[HTC One X] eteyen1:
Sorry to take you back to much earlier on in the thread, but I just had a question.

I regularly charge my phone from about 10-30% because of my work pattern. Should i be trying to charge it closer to the 50% mark? What sort of settings are you on, because despite my best intentions and efforts, I would be lucky to get 3 hours screen on time.

And what is the rule on battery saving apps, and if they are bad, can you explain why.
[HTC One X] farnsbarns:
Well, IMO you shouldn't. If you want to know something you should go and read about it, and probably not on fora, but, I do have a masters in engineering and have spent several years working in product design, specifically on a project for a series of mobile devices that ran on, wait for it, batteries! That was all some time ago but I have the kind of thirst for knowledge of new tech (not that li-po is all that new) that you might expect for someone of my background. I can assure you that I understand both the chemistry and the physics of lithium battery technology.

What I can't understand is how you fail to see the flaw in saying "I did it and my battery got better so it must be true" when it's common knowledge that the life of these batteries increases considerably in the first few weeks and the fact that everyone is telling you your findings are flawed. Even the links posted here contradict what you're saying.

I wont continue this conversation, the only reason I responded to your post was because it was so misleading and I wouldn't want anyone who doesn't know better to believe it, that way the misconception continues and spreads.

The facts for anyone who would like to know:

Li-Po batteries do not form a memory through improper cycling like the old Ni-Cad batteries did.

There is no such concept as calibrating a battery.

Android OS has a battery meter which may benefit from occasional calibration but the effect will be negligible unless there is a secondary issue.

The capacity of new Li-Po batteries does increase in the first few weeks of use, this is not effected by cycling 100% to 0%.

In an ideal world the best way to keep your Li-Po battery in good condition is to charge it from around 50%.

Flattening a Li-Po battery on every cycle will have a detrimental effect over time.

---------- Post added at 01:50 AM ---------- Previous post was at 01:41 AM ----------

Don't worry about your battery, the effect of charging from 50% all the time is probably as negligible as the effect of completely flattening it regularly, it really doesn't matter, that's the point.

Most battery saving apps kill processes, this is rarely helpful because of the way Android manages memory and causes a battery drain because of the increased processor time put into starting them back up.

I use my phone on the lowest brightness setting 99% of the time, turning it up when glare makes it necessary or to watch a vid et al. I use a home screen widget that allows me to toggle screen brightness, it also allows me to set the level for each toggle so it is truly at min brightness most of the time. This makes a significant difference to battery life, far more than anything else you could do. Min brightness on the HOX is perfectly good indoors IMO but if you decided 10% was the lowest you could live with then that's better than 50%.
[HTC One X] barondebxl:
Point1 you made, don't know about that.

Point2, I'm sorry but I can't take your word for it, I've read many articles that talk about battery calibration, android or not. I posted links on my previous posts.

Point3, occasional calibration? I thought you said there were no such things like battery calibration.

Point 4, fair enough, make sense.

Point 5 ,again I believe there's a calibration, obviously you don't have to drain the battery every time before you charge but I personally recommend it the first few days.

Love to discuss these things, I do believe you when you say you have a master in engineering, seeing how sensitive you are about the subject.
[HTC One X] spekesel:
I read the link. The Desire HD has a Li-Ion battery, the HOX has a Li-Po battery. Not the same when it comes to charging and whatnot.

Also, all the link is going into is

a) Checking the power draw on your phone

b) Draining your battery

c) Wiping the battery stats file

d) Charging

e) Draining again.

So....all that so that the battery stats file is a bit more accurate.

The idea of checking which apps stop the phone from going to deep sleep (ie: checking for wakelocks) is a good idea but thinking that a charge/discharge cycle will do anything is a debunked myth.

Still, like they say, you can't logic someone out of a position that they got to illogically.

[HTC One X] AJerman:
Actually, just to keep facts straight in the thread, Li Poly is a type of Li Ion battery. It's actually a Lithium Ion Polymer battery. They are basically the same, charging and otherwise.

But again, I maintain my previous position. The reason battery life gets better a few days after you get a phone, isn't because of charging cycles, it's because the novelty of the phone is starting to wear off a little and you aren't turning it on as much, loading as many apps, etc, whether you thought you were or not. After doing one of these placebo "battery calibrations", you leave your phone alone longer to see if battery life is better, and obviously it is since you're specifically trying to get the best battery life and touching it minimally. It's all in your head, people!
[HTC One X] prashj21:
I was having major problems with battery life even with light use and some features turned off. I work in lead lined rooms all day that block service half the time, so that doesn't help.

Yesterday I stumbled across somebody who suggested there is a file that tracks your battery life and that needs to be re-calibrated if you turned your phone for the first time before its fully charged.

he suggested that you let it fully charge, till the indicator is green. Then hold down the poweroff button untill the phone resets on its own. It will reboot and your battery should be re-calibrated.

I did that and now have been getting great results. Yesterday was the first day my phone didn't die by 7pm or at all last night. Today I've been on since 6am ET and am at 82% still. I would normally be below 40 by now.

Wish I had the link to give the guy credit.
[HTC One X] PhilipL:
Hi

This is an excellent source of information, and explains everything. http://batteryuniversity.com/learn/article/lithium_based_batteries

As for calibration, well typically calibration we are talking about here is just to give us a battery meter that reflects as close as possible to the real remaining charge in the battery so we know how much time we have left operating a device. Yes if you don't ever fully discharge/recharge then the calibration may drift out, so one day when you do fully discharge the battery it may be showing 20% remaining but shut down due to a flat battery, but you haven't lost 20% capacity, it was just the gauge that had drifted out. If this happens then you have now calibrated your battery for next time anyway!

From the article, which relates to smart batteries that try and keep track of energy flow in and out, typical for lithium ion batteries:

How often does a battery need calibrating? The answer depends on the application. For practical purposes, a calibration should be done once every three months or after 40 partial cycles. If the portable device applies a periodic deep discharge on its own [or the user lets the battery run flat occasionally], no additional calibration will be needed. However, if the equipment had been in constant battery power with no full-discharge interval for a period of a few months, then a deliberate discharge is recommended. This can be done in the equipment, with a charger featuring a discharge function or a battery analyzer. Avoid doing too many deep discharges for the sake of calibration because this would wear the battery down.

What happens if the battery is not calibrated regularly? Can such a battery be used with confidence? Most smart battery chargers obey the dictates of the chemical battery rather than the electronic circuit, and there are no safety issues. In spite of being out of calibration, the battery charges fully and functions normally; however, the digital readout may become increasingly more inaccurate and will eventually become a nuisance.

For a longer life time, lithium batteries last for more cycles if topped up well before flat and not allowed to fully charge. You might get double the cycle time by only recharging from 40% to 80%, however because you are only using half the possible capacity, you will be charging it about twice as often, so these things tend to even out and make little difference for the average smart phone. Just charge it as you like and don't worry about it.

Regards

Phil

I've recently been experiencing a series of pop-ups in an Android dialogue box occasionally when I click links that I know are clean.

A lot of them are dialogue boxes that say "Congratulations, your US number has been chosen for a gift - press the OK button to continue"

and the only way out is to either press the Okay button or force stop the browser.

The browser it most recently happened with has been with Dolphin Mini browser - can't remember if it occurred through my Android's native Internet browser or not, either way it takes me to a site called Mobgifts(dot)org

I did some research and some said it was a virus, but I have Lookout installed on my device and scan it weekly and just did a scan yesterday - all was clean..

TL;DR: Internet links in browser lately have been unescapable diallogue boxes that say "Congrats you won this" and you have no other options than to either force quit or press Okay then exit

I'm getting the same on my Cappy whenever I try to come to XDA. I just loaded Serenity Rom on the phone, haven't added any apps that I didn't have when I was on Cognition (other than BLN and Avast, in an attempt to see if the phone is virused. It's not. Supposedly).

I am royally pissed about this. I've had this phone for two years, most of it on some form of Cognition, and never had a problem. I literally can't imagine how these popups have wormed their way onto my phone--and for me, at least, what browser I use doesn't matter. Sooner or later, that damned popup shows up, and there's no way out of it except to FC the browser.

Looks like I'll be stripping the OS back to stock and starting over again, unless someone can suggest a solution beyond "turn on your popup blocker", since it's never off.

NOT happy.
