Yet Another Battery Tip - EVO 4G General

Well... I completely stopped charging my phone with the wall charger and I am now just using either my car charger or USB and i've noticed my phone over the last two days has probably doubled in being able to hold a charge. Today I made approximately 2 or 3 30 minute - 1 hour calls, used the internet approximately 20 times for about 5 minutes each time and used SNESnoid for approximately 1 hour straight and my battery was at 40% after a 10 hour work day, not too shabby. Not to mention I also don't get that annoying 10% drop within 10 minutes of unplugging the phone anymore
I've seen a ton of other battery tip's but I've yet to see any actually say stop using a wall charger all together. Here's to hoping this helps someone

Lol thanks for the tip. I highly doubt this is anymore then a placebo but good luck to whoever tries it. Not calling you OP I am just finding it hard to believe.
Furthermore, have you tried reseting your battery stats. I mean the initial 100-90 percent drop you are calling to quick sounds like its the fault of bad battery stats. If you need a link to how to reset your battery PM me only because I might not check back to this post lol.

Hmmm... I don't think that USB/Wall would actually make a overall difference in battery life but it could be that it doesn't "idle the charging" when you hit close to a full charge. So you're probably just getting the extra 5-10% that you mentioned.

I know for a fact im getting the initial 10% but I looked at my battery today at 12:40 tonight before leaving work thinking "ahh crap I haven't charged it it's got to be at, at least 5-15% and nope, it was exactly 39%, I was amazed. Talked to a girl for about 40 minutes on my drive home, talked to another friend for 5 and battery dropped to 35%

I've noticed this as well. Days that I've only used my moto car charger, the battery (even the cheap ebay ones) seem to hold the charge better, which I thought was strange, because you would think it would be a worse -maybe equal- change.

Charges more slowly and fills up more?

That's my theory

This is the case with most batteries, and I thought it was common knowledge with Li-ion. The lower the current you charge with, the better the charge.
Using the higher amperage wall charger lets you hit the voltage peak quicker but, the topping charge will take longer. A lot of car chargers are just as high amperage as wall chargers.
Other things you can do to try maintain the capacity of the battery over the course of its life:
-NEVER let it get hot (whether from heavy usage or keeping it in a hot car or the sun)
-never deep cycle (totally kill the battery)
-try to keep it between 40 - 60% charge for most of its life (Li-ion batteries do not like being at full charge or no charge)
Doing any of these things once will not destroy the battery, but by the 500th charge cycle, you can bet your ass it will.

Sounds like my kind of job! Seriously, I use USB (through a laptop) and car chargers almost exclusively and I have no real complaints about battery life. And by that I mean it gets me through the day, which is all I've come to expect from phones for the past few years. But I did happen to use a wall charger last night, and I have JuicePlotter active, so I did some checking.
Comparing my last overnight charge using my laptop's USB to last night's charge through a wall adapter, I found that the charging was actually faster through the laptop. I see that the charge tends to drop off as it approaches 100%, so I took pairs of points from uniform sections of each plot for my comparison:
Laptop USB:
44% to 82% in 41 minutes = 0.927% / min
Wall:
63% to 91% in 37 minutes = 0.757% / min

Hah, yeah my job is pretty amazing sometimes but I have def quit using the wall charger (unless I absolutely have nothing else around)
As far as for droiddev... this is my first phone where charging it from different devices gives me different results. I don't see where it would be common sense, Li-ion batteries are not supposed to not have these memory leak/hold issues like past batteries. A charge is a charge to li-ion batteries, but not in this case.

Not sure what you mean, but you will get the most life out of your battery by charging it short spurts at a time over USB. Read the article I linked to and you will see what I mean, but you can get the best charge into your battery by slowly ramping up in steps with a low current charger.

If you guys want great battery life, charge your battery in a TP2

That's right... For some stupid reason, our phones don't detect when the battery is ACTUALLY full. Getting annoyed with the having to charge my phone twice a day, I stuck my battery in my old Touch Pro 2 (left it powered off) and plugged it in... It took about 5 hours for it to fully charge and I let it sit for another hour.
I took it off the charger at 11AM... It is now 11PM and I'm at 68% and I've been doing more browsing and downloading than usual. Previously, I would have hit 20% by now and had to plug in the charger.
Once you charge the battery in this manner once, it should be fine from there because the cells have been fully charged for the first time. As long as you don't drain the device completely, you shouldn't run into battery issues.
Ordered a multi-function battery charge and two aftermarket TP2 "1500mAh" batteries from eBay, all for $11, hopefully they're good
I've been pounding the hell out of this thing today... I've racked up 8 hours of "active" usage... so actually I've used my phone more than normal.
The first clue for me was the fact that my battery didn't drop from 100% to 90% in five minutes like it was before... It would usually drop to 80 within an hour, even on standby...
It was at 92% when I got to work at noon.
Unreal, I never thought I would search ebay for a phone with a BAD esn
What I think is unreal is that our 2010 devices can't do something other devices have been able to do since 2006... AT LEAST 2006...
I'm running fresh .3 and I've had the phone unplugged for 1d 0h 15m and still have 30% left... so I don't have an issue with the battery at all.

I have two of these chargers and 4 batteries. I keep two at work and two at home.
These chargers top the battery completely off. I can take a battery that is "fully charged" in the phone and put it in the charger and it will still need 20-30 minutes of charging. The batteries off the charger will stay at 100% for up to 20 minutes, the ones charged in the phone plunge within 1 minute for me.
I really hope this issue can be fixed with a software update. Charging once a day is one thing, but having to take the cover off, battery out and reboot every morning is not acceptable. Not to mention that I rely on my phone while it is charging for emergency calls.

AFAIK it affects all HTC Android devices. HTC is lazy. Anyway I even put my old TP battery which hasn't been charged for at least 6 months in and charged it with the TP. It appears the first 5% is dead but it is still kicking ass and taking names over the charge I get from the evo.

Your battery was probably charged to capacity before they sold you the phone. Once a lithium ion battery has been charged to 100% it maintains its charge unless you screw it up by running it down to empty a few times. The problem is that for whatever reason HTC didn't see fit to charge all batteries to their max first even full well knowing that they won't get conditioned properly by the phone.

I did too, but think mine is defective. The batteries are pretty good for backup purposes and do their job. My wall charger sucked though. I had a Droid Eris hooked up via USB and a battery on the charger. After about an hour and a half, the Eris charged fine, but the battery was like at 30%.
Now the deal breaker is when I got home. I tried to charge a battery and my EVO via USB. When ever I hooked up the USB my phone litterally lagged almost would freeze to a point. I removed the USB cable and phone worked fine. So in all my charger sucked and can charge the battery but really slow.
I ended up just charging the batteries with the OEM charger and EVO turned off.

I think OP is talking about the TP2 OEM battery, not some knock off that you buy off ebay. FYI there are tons of battery for TP2, so it would have been better if the OP can tell us exactly which one he got. Check out batteryboss for comparsion:

Actually i was talking about putting your evo battery IN a touch pro 2 in order to charge all the cells.
So this is the reason why the EVO appears to be charging its battery so fast. I plugged it in, and it takes less than an hour to start beeping "I'm full."
......Because it's not really full.
That would explain why I was about to sleep, the EVO was charged, and I got an email, so it kept beeping every 10 minutes or so. which was annoying. I had to unplug it so I could sleep. I slept only 7 hours, and I heard the phone on the little table beeping again like crazy in the morning. I checked what it wanted, and it was the super warning that the battery was about to die.
No use at all in 7 hours, and the battery went from "fully" charged to almost ZERO.
I was almost crying of laughter. I just thought what a piece of junk. Hopefully I'm wrong.

Now, let's watch the soccer game, let's see how the USA does.

Why does this phone take so long to charge?

I have had it plugged into the mains, running tunein radio through wifi and its gone from 85% to 86% in one hour.
If I charge from 10% with phone off it takes about 4 hours to fully charge
If I charge from 10% with my phone on running stuff, it actually never gets to fully charges by the time I finish work...at 6pm
Sorry to keep comparing to the dreaded FruitPhone, but that would charge whilst running wifi and tunein from 10% to 100% in about 2 hours.
I am beginning to think my SGS2 is faulty
i am fiding it takes about 3 hours to charge from empty . It does take a long time indeed but i guess it is what we have to do for a 1650mah battery
3 hours from empty with stock charger .
jje
it might well be a 1650 battery, but it starts to get unusable when it takes all day to charge then a few hours to loose it all.
This phone is the greatest but the battery life just completely destroys it, I am beginning to think I made the wrong choice

Aye... if I don't the bloomin thing would be dead by lunchtime, and I listen to music.
So I basically have to turn it off not use it so I can charge it, how crap is that, owned my iphone a year never had any problems with battery and I always used and charged in its dock.
The desire had slow charging too but snq- fixed this in his kernels maybe we can port his fix to our kernels
btw it's true li-ion batteries degrade quicky when the heat up (or completely charge or discharge)
From 30% it took me one hour and a half to fully charge..
I recommend to download battery mix as it takes very good statistic on the battery life and one can tell exactly how long it takes to charge and discharge
Sent from my GT-I9100 using XDA App
just for the record all Lion batteries in phones never fully discharge or recharge, as there balanced by a balancing chip.
when you get to the likes of 0% you actually have 20% charge, thats why you can power on the phone but it will immediately switch off again. like wise, charging you never reach 100%, it's more like 89%, again because of how Lion works.
if you fully discharged and fully recharged, well put it simply you'd have a lot of exploding phones, fire and chemical burns...
Interesting!
My phone charges in about 2,5 - 3 hours, so should be normal...
But charging with the usb cable connected to the pc it takes much longer.
Any of you experience the same thing?

Because:
a) That´s how Li-Ion-batteries are charged. To fully charge a Li-Ion-battery you need 3-4h.
b) The power-supply is pretty weak. It is just enough to charge the phone at decent speed, but it is not enough to charge it and intensely use it the same time. In this case much of the power is used by the phone and there is not enough left to do a proper charging. I use a 1,2A power-supply from my old Nokia, and while it won´t speed up charging itself, at least it slows down less when I´m using the phone while charging.

This is not possible. The mighty fruity-phone may tell you it is 100% charged, but certainly it isn´t
You can charge a Li-Ion-battery very fast from 0 to 70-85% you could reach this in 1h. But you have to charge the remaining 15-30% very slowly, otherwise the voltage would raise too much and destroy your battery.
The so called saturation-stage (the charging-stage until 100%) takes longer the faster you charged at the beginning. If you really charged until the saturation-stage in 1h, the saturation-stage will take 2-3h.
If you charge slower, so you reach saturation-stage after 2h, the saturation-stage will only take 1-2h anymore.
In the end it will always take 3-4h to fully charge a Li-Ion-cell, regardless how strong your power-supply is.
Another few notes:
Charging will get slower the fuller the battery already is.
Using the phone with low battery-percentage will lengthen the charging-time quite a bit, a stronger power-supply could help.
Getting the last 20% in a Li-Ion-cell will always be very slow, usage of the phone won´t influence this a lot, and a stronger power-supply can´t help.
It doesn´t matter much, how much charge is left in the battery, to fully charge it it will always take long, as you spend most of the time in the saturation-stage (the higher the left percentage is, the more time you spent in saturation-stage)

The wifi is the killer, try turning it off when charging your phone..
Sent from my GT-I9100 using XDA App
it takes so long to charge because samsung capped the charge current at 650 mA in the battery driver. but other phones like HTC allow charging at the full 1 amp. so that's why its a slow charge, and why its possible to drain the battery even while plugged in to the charger.
Now who wants to ask kernel developers to increase that to .850 or 1 amp and use that lol.
I believe lack of heatsink due to design is the culprit behind decision to cap it at .650.

3 hrs to fully charge, and as i use tunein radio a lot i can tell you on my device with the screen off, wifi on with tunein running, it still seems to take no more than 3 hours maybe 15 mins more at most
I am probably going to order a cheap eBay Li-Ion battery that's 1800mAH and likely has a charge cap closer to 1000mAH. I will know in a week when I finally get my phone and report back if that battery helps. I expect it to heat up while charging and am going to use an external charger.
Two replacement batteries and an external charger go for about $12 USD on eBay btw.

[Q] Nexus 4 Charge time

Hello Experts,
I received a new nexus 4 and noticed that it takes around 3.5 to 4 hrs for complete charging from 5% to 100%.... is it normal? my other sony xperia seems to be charge in about 1..5 hr
since i am new to Nexus 4, not sure what is the avg charge time and should i call for RMA? Please let me know what is the avg time for charging.
thx
Ganu
Perfectly normal. You want a nice slow steady charge, especially in a sealed phone. The battery needs to last as long as possible. Fast charging batteries significantly reduces their lifespan. My old Nexus S takes the same amount of time to charge from 5%.. 3-4hrs or so give or take.. I still have the two year old original battery and it holds a charge just as well as it did the day I bought it. Meanwhile my 15 minute charge AA batteries I bought last year lose their charge in a week just sitting on the desk.
Mine is just about the same, but that's under use. If I don't touch the phone, it typically charges to 100% in about an hour.
And if it's through USB.. um.. more like 8 hours to fully charge.
Battery widget reborn (awesome app btw) says my phone usually charges in about 2.5 hours. This is on Qi though not sure about the regular wall charger.
2-2.5 hours for me on usb wall charger and Qi Orb.

From 2 hr 45 min (from around 12-15% juice left), my charge time has reached to 3 hr 30 mins now (i.e. from 1% juice left)... 14% juice wouldn't make such a huge difference so don't really know why it increased..

yes, this is one of the reasons i started this thread to understand what everyone is experiencing.... i called up the google customer support and they are ready to send in a RMA as it appears to be a higher side...
so let me know your thoughts guys...should 3.5 hrs charge time considered high and warrant a RMA? share your thoughts.
^ Hmmm.. I doubt if this would mean anything serious or worth RMA-ing. I can but I won't RMA my device because it's been exceptional so far. I am fairly happy with it and wouldn't want to get it replaced with a defected one.
Its perfectly normal especially from around 5% to 100%.. In my experience if you dont let it get below 20% it usually charges faster. I wouldnt RMA it especially if your phone is perfectly fine in other aspects.
I tried with a different charger yesterday and it took similar time. The charger has same voltage input levels.
You charge 3 hours, for only double the lifetime. How pathetic, actually. I didn't thought that the battery life would be that bad. I can hardly make trough 1 day, if I play some games, make some calls, and use a little bit of internet. On the last charge I got 4Hours of screen on time with 15% left.
Gosh, at least it's fun to use it. :/

Fast charging really is the killer feature of the note 4...

Cmon, lets give the credit where credit is due.
I no longer have to worry about battery charge thanks to this new fast charge thing. 45 mins after having a low battery I'm at 80%... thank god battery charging has finally progressed to this.
I use my phone for music / radio shows all day long. I can't tell you how happy I am to have this fast charge thing.. on the boat, in the car, at work at home, a 30 min charge and my phone is ready to go for HOURS!
Thank you to samsung and the note 4 for FINALLY putting a phone out there that is awesome!!

I agree but I rather swap my battery. When I get down to lets say 5% I don't have to worry about plugging it in. It takes less than a minute to go from 0% to 100% and it's less strain on the charging port and circuit. Plus if you still want to use the phone you don't have to be tethered to a cable.
+1 I love it. Swapping out the batter. LOL Not so much.
Battery swapping really sucks if you have a case on the phone. I vote for fast charging. Beautiful thing! I just need to get a fast car charger and I can charge my phone fully during my commute to work.

As an electrical engineer, seeing statements like this makes me cringe. I can absolutely assure you that there is no "strain" on the charging circuit, or battery, or anything else for that matter.
The only thing I could say is, possibly, the reduced battery life span due to the additional charge cycles. But charge cycles for modern Li-ion is already really high. But even if I were to entertain the fact that the battery might need to be replaced sooner, who cares. You are buying another battery NOW, vs the possibility of buying another battery in a year or so.
As far as personal preference goes, if a spare battery is your thing, go for it. But please try not to perpetuate the idea that the fast charging circuit or battery can't handle the charging.
I'm more than happy to go over the physics and electrical theory on how charging works. You might be interested to know that in a lab setting we can get charging rates as fast as 1 minute per 1000mAh with minimal heat build up (the major hurdle in improving charging rates)
Fast charging is nothing new. A similar concept are large capacitors, like a camera flash. They charge in seconds. The major engineering challenge is controlling the discharge rate, in most cases the heat build up is limiting factor.
Don't be surprised if the note 5 charges in 0 to 100 in less than 5 min.

i love everything about this post, btw. i'd love to know the physics and electrical theory if you ever want to share. it would probably help me to understand which is better for the phone, not that i need it right now, but i'm sure it would be beneficial to have that knowledge. i am one that is a fan of the fast charging, but i've also been looking at Samsung's spare battery charger too. the Korean Note 4 variants actually came WITH the spare battery charger (lucky ducks) but it's going for $45 ish right now on Samsung's website. might not be a bad investment at all, even though my battery life is averaging 12 - 15 hours on a singe charge.

Fast charging is nothing new. A similar concept are large capacitors, like a camera flash. They charge in seconds. The major engineering challenge is controlling the discharge rate, in most cases the heat build up is limiting factor.
Don't be surprised if the note 5 charges in 0 to 100 in less than 5 min.

This is true. I had an Energizer battery charger that could charge my AA or AAA batteries in 15 minutes. They got very hot though. This was in the 90's.

I had something like this as well. Mine had a fan on it that would attempt to keep things cool. I have an Ego lawn mower that can charge the HUGE battery pack that goes in it up by 50% in 15 minutes, and it sits on a big charging base with a huge, loud fan. That's a little different than charging a cell phone battery or AA/AAA batteries.
+1 on the fast charge thing. To me, that's revolutionary.
Fast charging is awesome, but I really don't use it. My battery life is so great the it easily lasts me the whole day with moderate usage. I usually end the day with 30+% left. The fast charging is an awesome feature, but i really have no use for it.
Someone was saying having fast charging checked depletes battery quicker. Ain't that some bs?
Has anyone given any numbers as to how slow / the rate of wireless charging is on this phone? I love fast charging but I want wireless charging as well.
I agree with a couple of these posts. I have moderate use on my phone and usually end the day at 40% or higher. However, I love having spare batteries that I can just pop in and be at 100%. Just ordered 3 plus wall charger for $20 shipped. Hard to beat having 3 full charges at hand if you don't have a chance to plug in for a while.
Battery life is great on this phone........period!!!

I believe most wireless chargers are 1 amp output. The stock wall charger is 2 amp so I'm guessing it would take about 2 1/2 to 3 1/2 hours to fully charge on wireless,I'm not expert though.

I do not doubt the usefulness of it, and I know it will come in handy some days. It's just my normals days I have battery to spare.

How and when do you charge your battery?

Do you let your battery drop down to 5% before connecting the charger? Or do you charge every moment you get the chance to keep battery at max?

Battery łasts a long time as it usually goes off the charger at 7 a.m. I charge it while sleeping. Occasionally out of habit I will charge it while I'm driving in the car but for about 15 minutes. Otherwise, I am very happy with the battery.

I'm not an expert, but all I've heard is charging over night or after it hits 100% is bad. Why I don't know, but I try to charge my phone when it reaches everywhere from 15-30 to 95-100 then remove the charger.

I'm not constantly on my phone, so usually charge it up to 80% and recharge when it drops to 40%. I only charge it to 100% when I am out and about for the whole day. See the following link for charging advice:

Overcharging won't happen on a advanced device like the S7.

Nah, that's old news. Modern chargers and devices know when they've hit 100%, so they stop charging at that point and lets the battery dip down to 98-99% before trickle charging up to 100 again, and so on until you unplug. It's completely safe, and you shouldn't trust all those garbage click-bait articles out there. Do not, however, go down to 0% before you recharge it. That can actually damage the cells in your battery, so plug it into the charger before that. If you notice some funky behavior from the battery, like if it's jumping from 30% to 20% in five minutes, or is stuck at 10% for an hour, then it's a good idea to completely drain it to 0% to calibrate the battery since the OS has no idea how much battery is left (so it knows where 0 is again). This will usually happen after flashing a different ROM. Charge it up to 100 again and it should be back to normal.
I personally charge it normally at night, without quick charge, since there's no point in having it quick charge while I'm a sleep for around 8 hours. I'll only quick charge it in the middle of the day, which is almost never, since the battery is freakin' awesome.
Don't worry about the battery too much, but don't reach 0% too often, and you'll be good. By too often, I mean every 3-4 months or so is OK. I base these things from my Sony device which I've had for almost 3 years. The (sealed in) battery was very good out-of-the-box, and it's still very good after nearly three years, so I won't mess with a proven success.
To be safe on the longevity of the battery I use one of these with my wireless charger :
http://www.amazon.com/gp/aw/d/B003P...mer+outlet&dpPl=1&dpID=31OAEbif0lL&ref=plSrch
My battery is usually around 30-40% at the end of the day. I use the regular speed Samsung Charging Pad and set the timer on this outlet for 3 hours when I go to bed. So after 3 hours it stops charging and I don't have to worry about the possibility of damaging the battery (I know about trickle charging, but I think this is better)
Ive read somewhere that the new s7 edge charger doesnt have a power inverter so it keeps charging and wasting power which could damage the charger or possibly device. So know if thats correct.

I just purchased one of those...thanks for the advice. I charge my device when get around 20%-30% of battery and left charging over night ( when sleeping) on my standard Samsung wireless charging. My battery is just ok.. I'm not so heavy user and sometimes I have to charge around 8pm or so. I take off from the charger at 100% all morning around 8am.

At home. I do wireless when ever i can. If im not using the phone then i sit it on a wireless charger.
Battery hasnt drop pass 30% in the week i had the phone.
My note edge would drop pretty low because i didnt use wireless charging. So my phone would just sit in my pocket slowly draining.

Whatever you read, either you misunderstood, or the person that typed it was a bumbling idiot. A power inverter converts DC power to AC. Your source/utility power is already AC. A USB charger is merely an AC adapter made for USB. The phone has integrated circuitry that controls when and when not to charge the battery and at what amperage.
I usually let mine get to around 5% everytime. Then charge it back fully to 100%.

Thanks for the details information. I figured the technology is so advanced with batteries that overcharging is in the past.

Not at all, but just try to not discharge the battery completely to the point where it turns itself off. It won't ruin the battery to the point where you actually notice it there, but it's better if you just turn the phone off if you're able to (unless it's an emergency, of course).

I never discharge the battery completely, like I said I use until battery is max at 5% [emoji3]

I charge it when it hits 20%. But i dont use the fast charging unless i need a quick top up
Does it hurt the battery to charge the phone with a different charger ?
Sent from my SM-G935F using Tapatalk
I never used the fast charging, I think that slowly charging a battery is better for the lifetime. Most of the time it is below 10 % before I plug it in and I also want it to be at 100% and ready (green LED) when I unplug it.
my note 3 battery is still superb and I got the phone since 2013
Best way to keep a battery in good health is to charge it to full before you start using it. Also, try and never charge it until it's less than 50%. Charging it overnight is perfectly fine it won't hurt anything but once ina while, at least say once a month let the battery drain all the way, try to turn it back on if it goes off sometimes there is still some juice left and it might start up, once it won't start anymore try and charge it without turning it on to full. I wouldn't do it more than say a couple times a month any more than that is overkill and may do more harm than good. These are the guidelines I use and I have never had battery issues. I currently am waiting for my S7 Edge and on my Nexus 6 I usually get 48+ hours with 4+ hours SoT. I'm just an average user currently.
