[Q] Samsung focus charging time

Hi,
Its been 6 months I am using Samsung focus. I am very happy with the phone but it takes exactly 3hours 30 mins to charge from 0% to 100%. Is this normal? or time to replace the battery? I do not remember how much time my phone used to do the same when I bought it. Please help :crying:

A few things you should consider:
1. Never leave your battery to drop under 40%. Get another charger or a secondary battery if needed. Batteries have limited power cycles. About preserving battery life read more in this post. Baseline: charge as often as you can.
2. How do you charge? USB charging is considerably slower than wall charger (500 mA vs 900 mA). For me, the original Samsung wall charger takes about 2.5-3h, from 0 to 100%. But as I was saying above, I tend to avoid complete depletion of the battery (as it reduces battery life) and charge often.

Thanks for your suggestion. I am using original Samsung wall charger to charge the phone. I am surprised that its taking 2.5 to 3h for you as well. Anyways, My wife has Galaxy nexus and it charge from 0 to 100% in less than 60 Mins. Is it Samsung focus which has this problem or almost all smartphone?
I take back on what I said about charging time on Galaxy Nexus. I tested it and taking 125 Mins to charge from 1 to 100 percent

Whoa, I seriously doubt the battery of your wife's phone is in good shape. If you're using a quick charger, it may show 100% in 1h but I seriously doubt it holds same as normal charge.
Most smartphones take at least 2h to charge. Don't take my word for it.
Here's a list of the best Android smartphones, made by CNET, to get the Androids list.
Here is Galaxy S3 (106 min = 1h:46 - considered one of the best smartphones as battery life, afaik), Iphone 4 (130 min = 2h:10), BB Torch 9800 (120 min = 2h) and even Galaxy Nexus (140 min = 2h:20).
LE: As I said, charge your phone as often as you can. For me, first 1h of wall charging shows ~ 60%. I always have a spare usb cable/wall charger with me (they're cheap and saves battery life) and I charge whenever I work or have a break from the phone.

awesome reply . I will now test galaxy nexus. I just posted what she told me about charging time for nexus. If its going to 100% in less than 60 mins ,i need to get it checked. Really appreciate your suggestions on this.
Can we leave the phone on charge before sleeping ? I mean is it OK to over charge the phone? Below is the link where I saw this information from
http://www.youtube.com/watch?v=hrcbcm11830&feature=g-user-u
Quick Suggestion:
Another question if you do not mind.. My friend is in love with windows phone. I suggested her to go for Samsung focus S as she needs bigger screen than focus and less than 400 US $ . What do you think?

Glad to help. I've also spent a lot of time understanding different types of batteries, to max out my devices. So let's answer one at a time:
Q: Can we leave the phone on charge before sleeping ? I mean is it OK to over charge the phone?
A: Yes, you can leave it to charge before sleeping. It does not overcharge, as the guy in the video pointed out. It's actually called "trickler charge", and whenever the battery's charge drops under a specific value (usually 95-97%), it charges again until it reaches 100% and so on. It doesn't overcharge.
Note: I charge my Focus at least once per day. My battery holds 80% of the initial charge after 1.5 years. Check my post I referred below and do read the 2 links there, to better understand today's batteries and how to max their life.
Q: My friend is in love with windows phone. I suggested her to go for Samsung focus S as she needs bigger screen than focus and less than 400 US $ . What do you think?
A: I would suggest a second generation device instead of Focus i917 as well (Focus S, Lumia 900). Besides being a newer model, Focus S has better screen, front camera and weighs less. However, I tend to notice women prefer smaller phones so you might want to clear that with her, first Other than that it would be a big yes.
Note: while the guy in the video seem to know what he's talking about, there are several important points he missed:
1. do not leave your battery to heat up, that damages the battery. You can do that by undercharging it using lower power than needed (that usually means lower amperage -mA- than required, and sometimes this happens over USB, as USB has only 500 mA) or evidently, higher power.
2. try to avoid your battery going less than 40% and charge as often as you can. I will just quote this from one of the links I suggested:
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while. Read more about Battery Calibration
3. it is actually important to calibrate your battery from time to time. Quoting from the same source:
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.
GL

Thanks for taking time for such a wonderful reply. That clears everything on battery issues. So my Focus is still going strong . Now I will try my best to charge the battery whenever it reaches 40%.
When coming to focus S , It is one of her requirement for a bigger screen than Focus (1st generation). She saw my wives phone (galaxy nexus) and started liking phones with bigger screens (less than 4.7 inches).
Cant wait for Windows phone 7.8 update and I hope microsoft is giving more than just the home screen update.
Thanks again for your help and appreciate it

I just got a Mint condition Focus yesterday off of Craigslist and it is working great. I 'm coming from Android (I still have an Atrix 2 as a back-up phone) and I'm exploring the Marketplace trying to find WP equievelents of the Android I like. I've found good many of them but theres one I reallly want. Is there a Battery Gauge app? I would like to see the % left. Is there such a app?

Battery life down significantly after 3 months...

Just like the title says, I'm not sure it's the last few updates but I'm on nougat. I'm not using power saving but I wasn't before. I haven't really changed more or added any new apps that I can remember. Can anyone advise if they have encountered a similar issue and how you fixed it?

Same for me. Battery has started draining significantly faster than before. I was told to go into recovery, wipe cache, and reboot but that hasn't fixed it. Although, I don't want too, I may be pushed towards an s8 upgrade if I can't figure out why my battery sucks now.

my battery has sucked from day 1, absolutely the worst phone ever for this. Nougat helped it last a little longer, but it still takes a year and a half to charge compared to past few phones I've owned. Charging from a 2.1amp car charger doesn't move but 3% in 3 hours. My portable battery charger is the same way, can barley budge the phone charge. Yes fast charge is on.
Note 7 and iPhone 6S + both charged just fine with the same vehicles and with the same portable brick charger.
what I still don't get is why with the same hardware specs for the most part minus the screen, why the note 7 was such a drastically better phone for battery life. I thought it was nougat, but that definitely wasn't it. I'm down to 20% battery life left by noon anymore with the S7E. Note 7 wouldn't hit 20% until 10pm at night (day starts around 7-7:30am)

You might have a defective battery. The fact that it won't charge up and assuming your charger is still good, is telling.

charges perfectly fine when plugged into the power brick. Used the same cable in the car etc. to no change. Just something about those it hates.
I'm finally going to breakdown at some point and restore it and start over just to make sure. next step will be to see if sprint will replace it. I am thinking I am going to buy an S8E outright here very soon...

Oneplus replacement parts availability for the next 5 years (battery, screen)

Hey xda,
I'm that kind of person who likes to keep his phones for 4-5 years.
To this day I'm still rocking my galaxy s4, many parts are available.
The oneplus 5 looks like a good phone to last at least 5 years, but as everyone knows, batteries fail, in my experience after about 2-2.5 years.
If I look for OPO batteries now, there only seem to be A: original OP batteries which have been laying in some warehouse for 4 years (bad for the battery) And B: third party batteries from questionable manufracturers (having bad reviews).
So my questions are:
What's your experience with oneplus 1/x/2/3 replacement parts (especially batteries) ?
Do you think it will be better with the oneplus 5 ?
(Should we push compagnies like RAVpower and anker to start producing op5 batteries? )
Thanks in advance,
nxss4

The oneplus 5 battery doesn't get hot when charged so theoretically it should last longer

Might be, but it also charges at a greater amperage. And eventually, it will fail..

It's probably too soon to see Op5 batteries on the market since the phone has only been out in Spring. And I think the OnePlus 3/3T was the first OnePlus phone that broke out of the niche market --and that phone is only a little over a year old so demand for new batteries probably isn't there yet. I would expect better choices becoming available for both phones since the OnePlus phones are becoming more popular. It seems possible this phone could last 5 years. I previously had Google phones and getting much more than 2 years out of those was like winning the lottery.

The phone may last, the battery not.
Batteries lose some of their capacity after a certain number of charge cycles, regardless what you do.
After a year or so, your battery will have about 80% of its capacity left. That's about 2400mAh after one year. By the second year you should be thinking about replacing it.

I think batteries in the past few years have gotten better. My one friend used his 2010 HTC desire for over 3 years before the original battery started to get weak (had like 70 percent of its original charge). His next phone I gave him was an HTC one s. The battery was still fine after 4 years when the amoled screen started to fail. Now he's using the 2013 moto x and the battery is still lasting 2 days like when I have it to him a couple years ago.
My galaxy s6 battery was still fine when I traded it in a few weeks ago. I've actually had quite a few older phones that didn't have any battery issues. The only ones I can remember having to replace the battery was a galaxy s3 I bought used and an HTC desire HD from 2011.
That said I'm sure we'll be able to get a battery because I do plan to keep this phone long enough to need a battery replacement. I'm guessing 4 years I will have to replace it.

With battery replacement costing $100+ you are probably better off buying a prior year midrange model than hauling around a clunker with severely outdated software for 5 years. For example, nowadays it is possible to purchase a Moto G5+ for around $220 NIB (there was a recent newegg deal).

Thank you so much for all the input guys!!!

5 yr old screen tech
5 yr old battery consumption and processor speed
5 yr old other tech (fingerprint readers, camera, GPS, magnetometer, light sensor)
vs
nearly lastest for all of the above for $100 more. Note that unlike your S4 the OP5 is a sealed battery so unless you have the right tools you cannot change the battery yourself.
Yo money yo choices

I can change the battery myself. I've had a few phones apart before. Its not that difficult. The cost of a battery will probably be like $20. The tech has gotten to the point where it's not improving nearly as fast. People will be using 5 year old phones 5 years from now. They cost double what they did 5 years ago for a flagship.

I don't know, I think the oneplus 5 is an amazing future proof devices, in 5 years galaxies will probably not have 8gigs of ram,
I don't play games so the 835 should be more than enough, fingerprint reader will still be one of the fastest (it's already kinda instantaneous) and 1080p works just fine for me
The reason I'm not going for a budget phone anymore is that've had bad experiences with budget devices in the past:
- The nexus 7 was unusable after only 2 years, freaking slow.
- The moto g2 is the slowest device I've ever used, I think it has some memory problems, it's slow on any custom rom I've flashed on it.
In addition to that budget devices just give a worse experience overall
Don't worry for the battery, repairing electronics is my hobby

That is an untrue statement. There is no set amount of time to determine lots of capacity. Look up BatteryUniversity.com and look for lithium battery page on charge cycles.
In short, never let your battery deplete completely. The depth of discharge (DoD) directly impacts loss of battery capacity. Your battery charge cycles is when your charge from more then 80% or less to full 100%. So for example... If you wait to charge your phone when it's under 25%, you will get roughly 250-350 charge cycles before significant lots of capacity. The rest goes like this... Charge at 25-50%, you'll get roughly 350-500 cycles and 50-75% 500-700 cycles and from 75%+ upwards of 1000 charge cycles.
My Nexus 6P was 18 months old and still had a capacity of 3100mah of 3400 (88%). So if you know what you're doing and take care of your battery, it can last much longer then expected expected.

How is my statement untrue? You just confirmed what I said.
No matter what you do, the battery will lose capacity. You can lower the amount of the capacity loss, but you can't prevent it fully.
And most people don't charge their phones until around the 30% range. According to you, that's about 250-350 charge cycles. And if you charge once a day, that's roughly a year.
So my estimate of the battery having roughly 20% less capacity after approximately a year was correct.
Not to mention the other factors that aid in the capacity loss (overcharging and heat).
Trust me, the average user doesn't take care of their batteries. I observed this at my friends and acquaintances. They always use their phones until it gets very low and then charge it.

I'm not staying they don't lose capacity, but why I said untrue is that you said batteries have a certain amount of charge cycles, and that will vary if you take care of your battery, and that after 1 year you will only have 80% of the capacity, and again, untrue. I was at 18 months and still at 88%.
I'm just saying is that is not set in stone and if people educate themselves on hour to take care of a battery it will last longer.

I'm also aware of this and charge my battery before it gets below 35 sometimes before 50. This is probably why so many phones I've had lasted well over 3 years on the original batteries.

Brand new S8 battery degrading.

So I got a brand new S8+ approximately a week ago. The battery has barely had 10 charging cycles and according to the fg_fullcapnom file my battery is already at 3244 mAh. And what's worse is that it's degrading with every charge cycle. If you're gonna tell me that it's due to fast charging then why does Samsung include one in the box if it's not suitable for your device. I intend to keep this phone a long time and if in the first week the battery has gone down so much then I can't imagine what it's gonna be at the end of the year. Any suggestions anyone can give me? Should I use a different charging brick? Like the original Apple iPad charger or a smaller/lower output charger. Or should I take my phone back to Samsung since I got it with one year warranty. But then again what do I explain to them, they probably don't even know what the fgfullcapnom file is.

Did I just get a lemon?

I got a brand new battery (Samsung branded, so "original") a month ago. But...it takes 1h40mins to fully charge from 0 to 100%. I remember the S5 took like 2h at the very minimum to charge from 10 to 100% some years ago with its first battery. Did I just get a lemon with twice as small battery capacity (Again, everything looks like the original battery. Says it's Vietnam-Korean and has a manufacturing date as well at the bottom left corner.). I flashed a stock 6.0.1 ROM to see if there was some fast charging option left enabled from the ROM/kernel I am on but it still said it needed around 1h40mins for a full charge from 0 to 100%. Wtf? Help, please
PS: I can get 4h SOT and around 10h total time with watching YouTube via WiFi for 2 hours and the other 2 doing other stuff around the web and other apps. But this charging time bothers me, it was not as fast as it is now.

Its possible, depending on where you got it from It could be a used battery. Do you see any type of nicks or scratches on the gold connectors at the top? Do you see any swelling on the battery as well? I got two batteries I use for my S5 and one is starting to swell and will not charge to 100% anymore.

Are you plugging the phone to any type of fast charger? My S7's fast charge plug in would charge other non- fast charge phones just slightly faster than a normal charger?
Grasping at straws here lol
You could ask the store to see if you could get another one, if that one is the same it maybe just normal now?
