Charging Issue? - Samsung Galaxy S9+ Questions & Answers

When I first got this I let the battery run right down and then charged it till full, till it said 'Charged' to optimise it however today (2nd charge) I waited and waited and it wouldn't move from '100%'................surly this can't be right?

How long did you wait? It's going to take a week for the battery levels to optimize.

I left it charging at 100% for about 10 minutes, even went for a shower while waiting so I doubt it was due to not waiting long enough

Battery stops charging

In the last week or so I've had an issue getting my phone to finish charging.....it charges to ~90%, then stops. If I hit the home button it finishes charging within 10 minutes. I've left my phone plugged in all night and woke up in the morning to find it charged to 90%, then in 2 minutes it says it's done.
I would normally just shrug it off and say well I guess it thought it wasn't done for some reason....however, I've noticed that if it doesn't say 100% when I unplug it, it's dead with about 3 hours of constant use, instead of my normal 5-6 hours of constant use.
Does anyone have any suggestions? I do really abuse my battery, given it's almost fully dead and charged 5 days a week....should I just buy a new one on ebay???
Rooted X10a flashed to global 2.1 well before these issues arose, and no new apps installed or changes made from the time my battery was acting fine until this problem arose.
The problem with X10 is when the battery is fully load the devices will cut the power- stop charging . So in the morning you got approximately that much.

Battery issues part 2

So the original battery in my phone.. well... sucked. When I pulled the phone off the charger it would jump down to 93% no matter how long it was on the charger etc. Any attempt to bump charge was thwarted in the fact that I cant charge the phone when its off (it automatically turns on and boots into CWM). Wiping the battery stats when the battery read 100% in the OS would still result in the above.
So I ordered that 1600mah battery from Seidio. Ran the charge out of it yesterday and charged it to full during the evening/night. Wake up this morning, pull the charger out of the phone, and BOOM 100% power. Not 93%...
So was it my old battery that was bad or was there something wrong with how the phone saw its power rating?
From what I've seen with the phone, it drops down to 90% or so before it starts charging again, but it won't ever have the display show a battery decrease while plugged in.

Right but I can watch the meter go all the way to 100%... pull the plug and it goes down to 93% within seconds.
funny thing phone did the same thing...took it off the charger this morn and it dropped down to 95
I'm at 99% after about 2.5hrs of mostly idle usage. I've been just rebooting the phone with it on the charger in the morning, give it about 15-20 minutes and usually it'll stick at 100

All you are doing is semi-bumb charging it, which is fine if you really must have that extra 1hour of battery, but be warned, doing it constantly will damage your battery over time. that is the reason the phone has built in charging/decharge in the first place.
The reality is if your phone is sitting idle, that 5% wont matter at all once your phone attunes to your battery, and if your using the phone so heavily that your going dead long before the day is done (after attunement) then the 5% still wont matter !
i was having the same issues - 90% right after unplugging. had to charge the phone 3 times in ONE day and i never even touched the phone the whole day except to check the battery percentage.
brought it into verizon, they gave me a new battery and now it lasts me the entire day. when i pull the plug out now, it drops steadily like a normal battery should. i tried bump charging before i brought it in and it didn't help at all
The same thing has been happening to my dads Thunderbolt.
He charged it overnight, took it to work and was losing about 1% per minute without touching the phone. The only time it was touched was about 1 timer per hour to take down the battery percentage for his log.
He took it to the verizon store and they told him he should not expect anything longer than 4 hours of battery life without touching the phone..what kind of BS is that?

I'm having the exact opposite problem with the batteries--just ordered two of the 1600 Seidios that delivered yesterday and even after running pretty much down, fully charging overnite with the T-bolt powered down, drops to 95% immediately. Conversely, the OEM battery would stay at 100% for hours if the phone was idle (screen off / receiving any emails and SMS). Go figger.
There is a post in the Android Central forums on the 1600 battery compared to stock. After testing, they found that the two perform almost identically. Basically, it isn't worth replacing unless you go with the big HTC extended battery. Although having a spare isn't a bad idea. If only that battery door wasn't so tough to pry off when you need to change it...
nexus s had the same problem its nothing big though

Most of us probably won't have the phones long enough to see any possible damage. Starting off at a full 100% is a lot better than immediately dropping to 95 or so after pulling it off charger. It's kind of like the gas gauge in my truck. Stays full a while but once it moves off of full you can watch it drop. lol

[Q] About battery life and charging

So I had my GS2 fully charged last night. At about 415am I played Game Dev Story for about 30mins and went to bed. I wake up this morning at around 1030 and find my phone completely dead. Obviously this freaks me out since I just got my phone and it should not be going from 100% -> 0% in 5 hours of being idle. Now maybe I didn't turn Game Dev off properly and it was running in the background? I don't know. I got this phone last Monday and this is the fastest it has died. (Even setting this one aside, I'm extremely disappointed in the battery life). Also, I plug it in to charge after I found it dead this morning and went back to sleep. Wake up 2 hours later at 12pm and see its only charged to about 40% and the phone is really hot.
Are these normal for the GS2? It didnt get hot during previous charges (atleast I didn't notice it getting hot). Also what is the average battery life for the S2 and how long does it usually take to charge from 0-100? For some reason I feel like there is something wrong with mine and I should be exchanging it but unfortunately I did root it so undoing the whole process will take some time since I'm still waiting for the jigg.
Normal charge time from zero to full 3-4 Hours via stock charger .
Excessive battery drain multiple posts on the problem .

I don't think anything is wrong with the battery. You can see the battery usage graph, and post if needed. And the device takes around 3 hrs 15 mins from 0 to 100% charge with AC charger.

[Q] Seven hours for a 100% charge?

That can't be right, surely? I know a lot of people swear by the initial eight hour or overnight charge cycle but I've never done it with any of my devices, and I've had quite a few. Anyway, picked up a Z2 this morning, used if for about an hour just to set up my Google account as install a few vital apps. Started charging it at 14% (from roughly 50% out of the box) and five hours later it was at 60% (with a further 2 hours to go until 100% according to the battery monitor).
The shop had closed I bought it from but I will bring it straight back in the morning. So, just in case I make a clown out of myself, the seven hour chrage has to mean something isn't right? My iPad Air didn't take that long, nor does my 17" Vaio.
The first few charging cycles will take longer than usual. It should sort itself out within a week. If it hasn't then I'd think about returning it.
Mine was the same when new.
Now I'm on 2h15 for a full charge.
If you look a bit more at the percentage, you'll notice that is is quite quick until about 85% and it slows down after, the last percent taking the longest.
Picked up a brand new replacement today. Started charging the battery after it had dropped to 4%
130 minutes untill 100% says the battery monitor app I've installed :highfive:

Not so fast charging

I have had my watch for almost 3 months and recently I've noticed that it is taking longer to charge. I used to be able to put it on the charger in the morning when I woke up and leave it on the charger until I left for work about 1 hour and 10 minutes later and it would easily charge from about 50% to 100% in less than 1 hour. Now it seems that I can only get into the mid 90's charging for an hour and 10 minutes from approximately 50%. I don't like to leave the watch on the charger overnight so I would like to be able to fully charge in the morning, even though my battery life is good and I don't run the risk of killing the watch with one day's use.
It looks like it just needed a restart. Charging nice and fast tonight.

same problem here since android 6.0.1
It seems to be hit or miss. It fast charges fine sometimes and others it is not fast. Last night it charged from 35%-80% in no time. I left it on the charger overnight and when I looked at it this morning it was stuck at 97% and battery stats showed that it had not changed since reaching 97%. I restarted it and it charged up to 100% within a couple of minutes.
