Battery not lasting as long as it used to?–SOLUTION
I’ve had my phone for a few months and I’ve always got at least 48hours of use and as much as 200hours while on vacation before needing to recharge. The last few weeks I’ve been getting less than half that. I’ve read that using a non standard charger that has a higher output overheats the battery causing degradation, and had feared that now I’d have to replace the battery which was quite disappointing since I’ve only had the phone a short while.
I’ve had many previous phones that have had their batteries last years without noticeable loss of capacity.
So I decided to run down the battery and do a “refresh” and kill the battery completely till the phone wouldn’t turn on. Then I charged it using the same non-standard charger which is an old blackberry one since I’ve misplaced my OEM one. I left the phone off and charged it up which took less than two hours before the green LED came one and read fully charged. I then turned on the phone and found that in fact it was only 66% charged, so I proceeded to charge it fully.
Well it worked! Previously I was losing as much as 20% overnight. After a few days its back working like new and only losing 2% on average whiling idling over night.
I’m not sure why the mini is so susceptible to battery memory, especially since one of the highlights of lithium batteries is their ability to be charged at anytime without memory effect.
I don’t think this is just memory issue, but possibly a software and hardware calibration issue. Where the phone feels the battery is fully charged while the battery hasn't reached full capacity.
A good way to discharge the battery is a 12V car bulb. Worked like a charm for me.
Thanks for sharing the tips.
I should try it on my mini pro.

I'm getting a replacement Maxx from Verizon and I'm curious if its better to drain the battery right out of the box than charge or should I charge it first? Or does it really not matter? I charged for 3 hours the first time not knowing what the LED lights meant and I feel like I was not getting the same battery performance others are claiming to get on these forums. I got 24 hours with juice defender, 4g on and moderate usage.
Just want to do it right this time.

For every post about to condition I could post to not to. I tried on several batteries on my charge several different ways and it never mattered. My Maxx I charged full the first time and get excellent battery.

While from the Charge that I came from it still has both points.
The manufacturers always recommend to fully charge first, although I've rarely been able to keep my hands off the phone long enough.
What actually does something for your battery life though, is fully charge, and then fully drain once a month or so.
This is NOT due to battery chemistry, but entirely due to the calibration of the battery software.
Older battery types needed this treatment to physically work better, li-ion revives this problem with this "anti catch fire and kill you"-chip
I was told many years ago to fully drain and then fully charge a rechargeable battery or else it would shorten its life span. Is this really true?
Currently, if my battery is at 30% when I go to bed I leave it alone and charge it the next morning when I get to work after it drops to 5% or less and just deal with not having my phone for a few hours during the work day. I would love to charge my phone each night and always have my phone usable throughout the day.
My concern is that if I charge my battery each nigh I will kill the battery before I can get a new phone.
What us the truth?!
There's a lot of confusion on proper battery charging techniques. Lots of people are stuck on the old ways of thinking, where you should let the battery completely die before recharging it or else the battery will get a "memory" and won't last as long. I won't pretend to be an expert on the topic, so hopefully someone else can chime in, but from my understanding you do NOT want to let newer style batteries die before recharging them as it shortens their lifespan.
That used to be true, but doesn't apply to the batteries used in phones today. You can recharge whenever you'd like, but you may need to 'calibrate' your phone from time to time to properly recognize an entire battery cycle.
Recently, my Droid Razr Maxx drained completely, and will no longer take a charge; very frustrating considering it's less than 2 months old! That's the problem with a non-removable battery. Very expensive paperweight.

The truth...found
Found this....the science of modern batteries. Lets hope it works for our DNA's.

that article applies to our battery chemistry. Personally i still use my phone as a beside clock and keep it charged overnight and discharge it to whatever % it's at at the end of the day.
Hello everyone. First off, I have read this - Things You Should Know About Lithium Ion Battery. Secondly, I know this smartphone has a weaker battery than most, which combined with a dual-core 1ghz CPU makes it drain in about two days on average (I am an entry-level user). However, I've managed to optimize battery life through various options and by staying on factory Android (2.3.7) so now it can last to about four days, so I was very happy. Now more about the 'incident'.
Usually I charge my phone at home on an unused wall socket. But this time I charged it at my friends place on an extension cable which was literally packed with cables and his PC stuff. First thing I noticed is that it took a lot longer to charge my phone. It took nearly two hours to charge my phone from around half capacity to full, while at home this is usually accomplished in 30 minutes.
After this I've noticed that battery life deteriorates much quicker, it now lasts about a day and that's when just idling and not doing anything (!), so I'm back to the state before I managed to prolong battery life and even worse.
So what happened? Did my phone suffer irreversible damage to the battery?
As much as I can tell from a layman point of view, the AC flow on that extension cable felt 'unstable' so maybe it means the battery was charged with 'lower quality' current?
Now every subsequent charge I do at my home improves battery life for the first few hours, but after a point it still deteriorates rapidly and that's while my phone is not even awake. I get the feeling I should let it discharge completely (even though this is not advisable for Li-Ion) and charge it fully from zero to full capacity? Kind of letting the battery format again in normal conditions maybe?
Much appreciated. Luka from Serbia.

This is how my battery life looks after 22 hours. As you see, most of it was when the phone was not awake.

Here I drew a green line to indicate how my idle battery life looked like before.

Even using 2.3.7 that's not normal... your problem it's not from that "episode". It's from the past
i am havin HTC AMAZE 4G
when i used to charge it before
phone used to come to 90% from a full in approximately 1 hour.
now it comes very quickly like 10-15 minutes
& also the major problem is my phone gets switched off at any battery percentage like 65% & when it gets restarted it comes to around 8% or sometimes even 4%.
if i pull out battery again restart the phone then sometimes it comes to around 30% back or any random increase in battery or sometimes even decreases to 4% & then the battery gets drained in 5 minutes & i have charge it again
battery takes more time to even charge
sometimes using DATA & charging it even takes 10 hours to charge
i dont know what is the problem
i have been thinking about battery problems
but i googled & in some blogs it shows as circuit problems too
the problem is i am living in INDIA
this phone is not official here so the service center guy wont touch it & i dont want to waste money on the battery if it isnt the problem
USING HTC ICS OFFICIAL ROM
NOW BATTERY LASTS with normal data on maximum 4 hours
help me out guys
thank u
How old is your handset? Battery life decline is normal as it ages. Without being able to inspect and test yours out all I can tell you is the most likely explanation for what you're describing is battery wear.
The original HTC battery that came with my phone only holds 2/3 of the charge it once had when new, which is why I invested in a pair of Anker batteries and an external charging station (I purchased them together in a package on eBay for under $30 US shipped). Having the extra batteries has been an excellent addition. I alternate them every few days to more evenly balance how they are wearing and to prolong the remaining life of my original battery. Plus it's great to have an extra battery to use for those times when I really need my device, but don't have the ability to plug in.
Check out the best battery thread in the Amaze accessory section for more details and comparisons.
I hav been using this phone for 1.5 years
tried using battery of my dad he uses same phone.
It showed 56% in my fathers phone
Wen i switched the battery &; started my phone it showed 15% at start
So what could be the problem then?

You're getting the different results because the batteries aren't calibrated to each phone. If you put your fully charged battery in your father's phone it shows 56%, correct? What happens when you put your father's fully charged battery in your phone? Keep in mind that when switching around the batteries neither with be calibrated to the device, but will instead show a percentage vs the battery that was properly calibrated.
Example: the battery in my phone shows as fully charged, but is worn and no longer charges to the maximum. If I place it in my brother's Evo 3D which uses the same size battery but is newer. It will show as only partially charged because his device is calibrated to his newer stronger battery. Conversely, if I put his newer battery in my phone which has been calibrated to my older worn battery it will appear to be fully or nearly fully charged for a long time before it begins to show it's draining with use.
The only way to properly test your battery would be to either try a known stronger one in yours for several charge - discharge cycles as your phone calibrates to it, or to try your battery in another device for several such cycles. Then you need to compare if there was an improvement in up-time or not. Short of taking it in to be checked on diagnostic equipment it's the best method I can think of.
Good luck!
Thank you very much for the reply
Goin to a local mobile repair guy for a hardware check
Will tell you the results tommorow
Thanks once again
Maybe you just need to wipe battery stats. One trick that works is let it drain completly and let it be drain over night and charge it again keep doing a couple of days it may just get better. But think is just battery problem not hardware related.
My Original HTC battery worked its way down to 2 hours of usable talk time. Eventually, got so bad that it barely charged on anything but a high current wall charger. Technically it was under warranty at the time...
Ordered 2 Anker Batteries w/ charger for $30, and not long after that the charger broke. It quit charging batteries.
I then just stuck with one Anker battery in my phone and the other as backup. The battery I used the most is now down to about 4 hours of life on a full charge. The least used is about 8. I try to keep the worse one charged up as a backup in a pinch and now use the good battery full time.
Just how life goes sometimes...

Yeah that Anker charger is the weak-spot in that 2 battery package deal. The damn thing is flimsy and fragile. I'm so paranoid about breaking it I treat it with kid gloves. The batteries are pretty good though. The package was one of the best investments I made since owning the Amaze. Using indelible marker I labeled them 1 and 2, and rotate their usage with my original HTC (which is easy to distinguish). This way when I'm on the road I always have one fully charged spare handy, one charging at home, and one in my handset.

Agreed!
But When I was using official ICS from T-mobile, I had the same problem, even after wiping. I even faced a funny thing. Percentage of battery in bar was different from percentage shown in lock screen!!!
After flashing custom rom, All problems GONE!
Hi
I use my V30 as Hotspot the whole day and this sucks battery quite quick. Is it problematic if I keep the power cord (usb-power-plug) connected all day long? Does the phone still use the battery in that case or does it just draw its power from the power cord and only recharge the battery if it drops volatge by self discharge...

I'm not sure I believe that site... I have been a fan of Battery University, but in my experience they got this wrong. My Droid Turbo battery lasted for 4 years before I switched to the V30. I always charged it and left it charging overnight. My laptop that I'm typing this on now, has the original battery from 8 years ago, and it's still working. This laptop stays plugged in almost all the time. Certainly, it doesn't have the life that it would if it was new, but it's been 8 YEARS.
In my case, I keep my devices pretty long, and it doesn't cause a problem. So, I won't bother to unplug at night... it's not worth the hassle. Most people would upgrade their hardware well before these times, so they would notice the problem even less than I do.
The bigger issue I see is when it the phone overheats. My work phone (in my crappy work car) sits on a mount on the vent, which (because of the crappy car) doesn't close completely. So, this winter, it got very hot relatively often. That has hurt the battery life on that phone (a Turbo2)... which now has much less life than my Turbo does. But, it's a company phone, so they're going to replace it... not my problem
The other issue I see is charge cycles. My wife's laptop was often charged, then run on battery, then charged, etc. The battery on that laptop was only about 3 years old when it stopped performing (wouldn't even run the laptop for more than 10 minutes). IMO, charge cycles are, therefore, more important as than overnight charging.
Just my $0.02... feel free to disagree if you want.
Exactly! Charge cycles!
I only charge my V30 every 2nd or 3rd night for that reason, and I still get 7-10 hours SOT after 1.5 years, depending on how much music I play in addition to the SOT.
That said, it's also best to avoid draining the battery too low. The chemistry suffers the most when it's very low or very high.
Keep in mind, with charge cycles, they say it's proportional as well. So, if you charge 25% for 3 days in a row, it's the same as charging 75% every third day. I prefer to keep the phone charged as much as possible, in general.
Also, I neglected to mention, my overnight charger is a slow one (not a QC one). That way, it's slow charging overnight anyway. This speaks to the heat cycling of the battery - QC does heat it up more than a slow charger would. That's also why I don't wireless-charge, as it adds to the heat, too (at least it did on my older phones)...
