What's the typical lifespan of the battery?

I'm just wondering... if I intend to keep my Incredible for a while, should I plan to replace the battery? Do these batteries wear out and if so, what's the typical lifespan?

I don't know a lot about battery but I supposed it depends on how you use it, charge it, heat/overheat, etc. My incredible is 13 months old and the battery is about the same, maybe. Just remember OEM batteries/parts is the best.

I would agree with respect to sticking to factory/OEM batteries. I bought a second HTC extended battery when my first one seemed to be losing a charge faster than I thought it should. This was after about 14 months of hard use. However, I also bought an external charger which allows the battery to get fully charged to 100%, whereas I found that the phone was not charging it all the way up (most likely due to bogus values in the battery stats file). After rooting, installing Pete's BuglessBeast GPA19, and re-calibrating the battery I'm getting about 24-30 hours out of a single charge on both the new and the old battery...

Another Gold 3500 battery review...slightly scientific

Wanting more battery life and having reading a few positive reviews about the Gold 3500, I got one from Amazon (UK). The numbers 3500 vs 2500 mah indicate I should get around 40% extra battery life compared to stock but having played with RC cars and helicopters running LiPo packs I know that pack ratings aren't everything.
Actual battery capacity depends on the discharge rate, the more juice you pull the less the effective battery capacity you get with a lot of energy wasted in heat due to internal battery resistance. Fact of life with batteries of all chemistry.
My original battery is about 6 months old now, charged daily from anywhere between 0-50% remaining. In day to day use the Gold does seem to last longer based on my 6 months experience with the original battery but how much better is it?
I charged the batteries in my phone and turned the phone off once it hit 100% but kept the charger on as it seemed to charge for a bit longer.
Using my RC battery charger, I used the discharge function setting the low voltage cut off to 3V (standard for lithium batteries) and set the discharge rate at a constant 300 mah. Using a constant discharge rate may not be realistic but it does allow for a fair comparison, keep in mind that our phones power usage jumps up and down depending on use.
Results
-----------
6 month old stock battery rated at 2500 mah = 2364 mah (which is what I would expect from a battery with 180 cycles on it)
Brand new Gold 3500 rated at 3500 mah = 2524 mah (a bit disappointing but at least as good as a new stock battery)
Now the discharge rate can make a big difference to effective battery capacity, it might be that the 3500 mah rating on the Gold batteries was determined using a very low discharge rate or they discharged it to below 3V.....or its just a gold wrapper over a stock battery
Interesting to note that the stock Sammy battery is pretty true to its rated capacity, so the perceived increase in battery capacity I experienced with the Gold battery is probably just the difference between a 6 month old battery and a new one.
Oh well, at least I have a spare battery now and didn't pay a fortune for the Gold. The Gold does seem to last a bit longer than the 6 month old stock on so I am happy enough with it.
Notes:
Gold battery had been in use for 2 weeks to run it in
Only one discharge cycle was performed
Could be that I have a dud battery, you results may differ
In real day to day use the discharge properties of the Gold may result in a higher 'effective' capacity
Solar flares are the source of all coding errors
Fairies do live at the end of your garden :cyclops:

It's a shame i've read this post only two days after buying me one of those. Anyway, even if it won't last longer, i'd still have a spare battery right? So everything is not lost

nope, its a shame they rate it 3500mah if this is the case for all.
Mignon, maybe your can get a replacement from thrm and test again. Especially if you have a dud.
Do notice I notoce a significant increase in battery life after charging it past 100%. Probably placebo, I dont know.

Don't think I have a dud, in my experience lion batteries either work or don't. It's not a crap battery, it's just as good as stock but doesn't match the advertised 3500 mah rating.
And it's shiny gold so things aren't that bad

Well that sucks.....haha...i order a gold a week ago.....it should be here soon.....

I got 3500mah gold battery. I review it.
My rom is ultimate rom v5.1, and my stock battery was 11 months old.
Screen on time was always less than 4 hours.
Yesterday I got the gold battery, and I used it up to 1% without first charge, then I charged it 12 hours to initilize the battery.
So unpluged the charge, and tested it as the same usage. I always downclocked to 1000MHz, wifi on, no use 3g data, brightness is zero, bluetooth and gps is off. I downloaded 15 files and apps today, listened to music, did multi windows function, and almost used web browsing.
Now my battery is just 1%. Screen on time is over 5 and half hours. Obviously the battery was improved.
If official JB are released, the battery will be improved more.
But this is not made in Japan. This is made in China because Japanese is so strange on package.
Some of Chinese battery are so dangerous and may be fake, but this gold battery is good one.

I dropped my stock and it works perfectly till 55% then it dies. Gonna throw it away soon. So some of the cells could be damaged. Its not either they work or dont m8.

@Mingnon thanks for your effortful tests.
@eeynjae, what are all apps spreading around those icons in your notification bar ?

I am pretty sure most mobile 3.7v phone batteries are single cell, only the mugen styled battery extender jobs that require a different back cover run two cells in parallel.
Remaining capacity is usually just a function of cell voltage so it's strange that it should just tank at 55%. Battery protection circuits generally prevent discharge past 3.0 volts so not sure what it's going on there.
Either way it sounds like you need a new battery, wouldn't risk recharging a damaged cell...

yeah its strange. Stuff started to happen at 50, whrn restarting bat percentage dropped to 10-15%. Without restartingbit would go down normally in beginning. Now after using it some time and dropping it its 55%.
Its definitely it either works or doesnt.
Anyway I dont think it's single cell.

i have the same battery bought it a few months back i'am very satisfied....
it's not a 40% extra time even framework it designed to work with less voltage since after using it below 15% i notice always fake meter value, when you keep your phone asleep for half an hour you will notice an increase in percentage. not accurate but runs fine, its a spare and a great replacement i dont care if it's slightly powerful than stock at least its the same size for 4 extra hours.. i never needed to change case nor a cover of anything its great

Sorry for my off-topic question, but i see in this topic there are advised people recently i bought a noname car charger for my Note, (specs: output 5.5V DC, 800mAh) - is this charger good for the Note or it would damage it? (i read somewhere that the original car charger's output is 5V... this difference of 0.5V has any importance?) Thanks.

Thanks for your time and efforts - your results are similar to my amateurish measurements performed twice and reported on the other 3500 battery thread. Having no device to test the actual capacity, I just used the continuous video playback in plane mode with minimal backlight. The time to full discharge was almost identical in both cases.

It won't damage your phone, but if you are going to use it as a gps while charging, it will probably keep dranig the battery, 800mah is not enough to charge it while screen is on and gps is running

Why is that?
After i've received mine, i've never ran out of battery during my day. Definitively improved the usage of my phone.

[Q] Battery dying, should I buy an external charger?

Bought my phone on Black Friday 2012, bought a spare battery about a year later, and now both batteries are virtually gone.
The (newer) battery has bloated significantly and is now officially retired. AFAICT it was completely original from Samsung, with NFC. The older one lets the phone go on only if it is charging, and then holds for maybe 3 hours of no or little usage.
I admit, I haven't followed the advice of keeping the battery between 20 - 80% charge, and other maintenance, so I'm willing to believe this is what was expected under the circumstances. Is it?
AFAIK there is no app that can display the true capacity of the battery. Is there by any chance a testing app that measures how long it takes to drain under a specified controlled workload, and hence find out, somewhat accurately, the capacity currently?
Now I wish to buy 2 external batteries + a external mains charger for it, and actually do some maintenance on it for its life. Is that advisable, or should I only charge a battery inside the phone?

Bump... no one?

Worried about unremovable battery

This will be my first phone with a battery I cant replace. Batteries lose a lot of capacity and will be down to something like 75% after 12-14 months. Has anyone got a battery replaced on previous models? How much did it cost? What is the battery capacity loss like in general on HTC phones? Thanks

The battery on my m9 has kept itself together well considering it's a year old. I have flashed the sense 8 launcher and now the battery is as good as when I first got it. I wouldn't be worried bout that mate

I haven't had a removable battery since the a Nexus 5. My Nexus 5 turned into a media player and it holds a charge for about 3 days easy. 5 days when I rarely touch it. It's almost going on 3 years old. I don't miss a removable battery all that much as I thought I would.

You also have QC 3.0 and the HTC charger has some cooling tech, so the battery should have a better lifespan than previous iterations anyway.

the point of having replacing battery is to carry one with you at all times to replace it, right?
I think, if you're gonna carry something i would rather have a power bank, less dangerous to have around and takes way more battery and you don't have to remove the battery to use, yes it has to be connect to the phone, but hey, everything has pros and cons.
I prefer the power bank and i also never had to change a battery because it lost quality, but that's me

No, I replace my battery every 6 months as batteries lose capacity, after replacing it, I always get a big increase in battery life, after 1-2 years, it may only holding 60-70% of original charge

You must be doing a lot of charge and discharge cycles a day to wear it out that quick...

So I've had my M7 since I pre-ordered it April of 2013. Still the original battery. If I unplug the phone at 8am and use it normally throughout the day (occasionally browsing reddit/YouTube, texts/messenger/emails during downtime), it probably lasts 8 ish hours without charging it at all.
Not sure if that helps. Can definitely tell it's degraded a bit since I first got it.

Your phone doesn't get to 100% in 5 seconds with a power bank, a replaceable battery does. A replaceable battery is a lot lighter and smaller than a power bank. And who wants to use a phone with something tethered to it?

if you're using the phone you're most likely not moving a lot either, which means you can easy stay still and connected to the power bank, there are small power banks and some even give you quick charge option, but like i said or meant to say, use whatever you want and think it's better for you

My M8 was purchased on day one and after two years of use it's still going very strong. I don't notice any significant differences from my initial impressions.

How do you calibrate battery?

M7 three years old. Always get 4 hours plus sot. Even got seven when reading heavy. I wouldn't worry, just don't charge all night, buy a timer.

Attached the wrong one, even though it was good too.

Batteries are odd things, especially Li-polymer batteries.
Like above, my M7 is 3 years old.
I get 14-20 hours average out of my phone with a LOT of web/email and poor coverage (mentioned because it sucks more juice in thinner coverage). Currently I'm on 13+ hours and have 17% left.
The real damage to these batteries is # of charging cycles and heat. Heat prematurely wears out the chemicals and each time you plug into charge you're killing one of a limited amount of charge cycles.
You should not see a true decrease in capacity as these don't have memory effect.
I'm a horrible user in that I often plug into charge when in the car and tend to run my battery way down before recharging, both of which are hard on a battery.

When you get a new phone there is not need to worry about this at the beginning, but after 2-3 months you should think about doing a full discharge, from 100% until it turns off, even after it turns off i don't plug it right in, i try to boot it 2 or 3 times and let it turn off by it self again, then just charge it 100% again, this should help is some cases (do this procedure only once a month maybe, there is no need to do it all the time because it will put strain in the battery and if you do it a lot you will also lose battery life).
Another thing to keep in mind is that tests have shown that if you can, you should charge your phone at +-50% (instead of 20% or less) until 90-98%~, of course not everyone has the time for this but it's something that helps maintain battery life.
Battery's also need exercise and keeping the battery plugged in a lot won't help, if you can avoiding stressing the battery with high temperatures as this also reduces the battery life.
There might be a few more tips for battery's but this is all I remember/know for now, hope it helps :good:

Phone abruptly dies under 20% battery

Phone totally goes black/dies when battery is 21% down to 10%. does this just mean the battery I have is bad? What replacement battery is best? I've read Anker makes a good set with charger. Thanks.

Samsung SDI batteries are the only batteries I've known to do this. When screen goes black, that should be a shutdown. Do you plug in your charger at that time? Mine actually actually showed 0%.
It's inconvenient for a battery to shutdown unexpectedly, while showing capacity remaining. I always replace Samsung OEM batteries with another brand. I found one that I liked so l went to Amazon and bought a second plus external charger from same brand. If looking at another alternative, just search MPJ and read the reviews. The battery and wall charger were on sale last week, maybe still.
If you're considering upgrading to sealed battery in unibody phone, you should consider the care required for such a phone to get battery to last. Sealed batteries are actually very similar in capability and ratings; no leap in tech but apparent shortcoming evident in Note7 embarrassment. Fast charging produces heat and steals life from battery's endurance down the road. Studies have shown since lithium batteries have no memory that you're actually prolonging the battery by slow charging without load or minimum load and bump charging rather than cycling battery to near 0% then back to 100%. Manufacturers don't tell you that because they prefer you wear your battery down in less than a year's time and consider another phone purchase.
Maybe Samsung would be better off today if consumers were more aware of how to prolong lithium batteries?
If you want your battery to last two years, bump charge it after 25% used as much as possible; it shouldn't even matter if you bump charge it 3x per day. Avoid fast charging and heat cycles. IOW, try not to use it while charging; the cycles should be short anyway.
Or, if you prefer to abuse a removable battery like the Note 4 and care less, pay about $15 and just replace the battery every year. 500 full cycles is all these batteries are currently rated for due to increased degradation with abuse. Mini cycles allows more of those cycles without degradation but you'll still have capacity when you need it to last a long day without charging.

Try this, if you are rooted and have recovery wipe dalvik cache and cache. Power off phone and pull battery for like 5-10min. Hold the power button (with battery out) for like 1-2min. After letting battery sit out for 5-10min reboot and see what happens. If same instances occur. Your battery is dead just purchase a new one! Anker recommended!

You're welcome.
Bump charging is partially charging before battery gets low. An example would be running the battery down 25% and charging without overcharging it.

Had the same issue, bought a new Anker and issues resolved, the stock Samsung sucks!

I'm just glad there's a way to replace it that'll mean this phone can last a long time if I'm careful with it.

Yeah it must be these batteries. My mom has the Note 4 as well and hers does the same thing. As does mine

Yes the stock Samsung batteries are horrible. They don't last very long then they start misrepresenting the battery statistics to the OS so you get the shutdowns at 20 or so %. I switched to a twenty$ Anker I found on Amazon over 6 months ago and never had the issue occur again. Even thy sprint techs will tell you if you ask them outright!
