Problem #1: Causes of Galaxy S5 fast battery drain issue

I know you hear this all the time, but I’ve yet to read any solution.

My symptom is this: My battery is draining at an all-time mega-fast clip. I mean FAST. If I am using the phone at all, I am recharging up to 4 times a day now. What separates me from anything I’ve read so far is this: I’ve noticed that with every single update to the OS of any kind, the battery has drained faster. Without question. When I first got this phone within weeks of its release, if I had never updated it, I would have been one happy camper today. It was lean, mean, fast, and held a charge for a couple of days. I was deliriously happy with it. Then came the first update, and it’s never been the same since. I’ve had a host of other problems post-updates, just like everyone else, but this battery thing has almost defied belief — and I wanted to share with you my observation since I’ve been with this phone since the beginning when it was first released and through all subsequent updates, with each being worse than the last related to battery drainage.

I have no new 3rd party apps installed. Any that I had are long gone. I am down to the same core that I’ve been using for most of the past year — ones that I know are rock solid. I have installed, uninstalled individually, by batch, reinstalled, uninstalled again ad nauseum other apps until I am back to my core batch again. And NOTHING has made one iota of a difference in the battery. I have downloaded, used, dumped, installed another, used, and dumped the top-rated battery utilities, and they do virtually nothing to improve the situation.

Now I’m at the point where I wonder if maybe the battery needs to be replaced through attrition? I don’t know. I’m dumping the phone to get a new device here in the next couple of months, so I’m not investing in another battery regardless. But until I get another device, it sure would be nice to know if you have heard of anyone else reporting this same scenario, and if so, if you’ve had any successful strategies for solving it.

By the way, I’ve dumped system cache about a thousand times, I’ve rebuilt from scratch, I’ve done all the usual troubleshooting steps — all to no avail. Yet, as I said earlier, when I first got the phone, before the first update, this phone was a gem. Now I hate it, I hate Android, I hate Samsung, I hate Google, I hate Thomas Edison, I hate …

Lithium-Ion batteries are limited

Now to the issue at hand. As portable devices become more advanced year in and year out for a good part of our digital lives, there’s one aspect in this smartphone revolution that didn’t much at all — the battery. The power source of even the most expensive and powerful smartphones today still suffers from this perennial weakness. As smartphones gain wider, bigger screens as well as more impressive processors, the Lithium Ion battery that powers them has remained technologically dormant. It’s not uncommon to know users don’t have a full day’s usage before that call to charge rings again. As smartphones become more power hungry, the power source in the form of existing Li-ion batteries are apparently unable to keep up.

The only way to ramp up battery capacity today is to make it bigger and thicker. Ever wonder why a 10050mAH Power Bank is that thick? There is no arguing that manufacturers can equip their flagship phones with higher capacity batteries but that would sacrifice aesthetics and weight considerations. The only way to increase battery yield today is to physically increase the battery itself.

Blame it on chemistry

Lithium batteries work by transferring Lithium ions between electrodes — a Lithium-Cobalt cathode and a Graphite anode — in a cell. During a charging period, the battery siphons ions on the anode, and when you use the phone, the ions are moved to cathode. This process of moving the ions between the electrodes is called “cycling”. Overtime, after several cycles, a film of Lithium atoms are collected in the anode and remains there. After each charging and discharging (or cycle), more layers of atoms are deposited to the anode, which results to reduced capacity. You repeat this process day in and day out for about a year and you have effectively reduced the capacity of your battery.

For some unlucky ones, both cathode and anode electrodes can get coated with a film of atoms, resulting to a more abrupt drop in capacity level. Such situation can lead to an irreversible capacity loss very quickly. This is the main reason for a more noticeable fast battery drain issue we often encounter from many members of our community.

So what can you do to extend battery life of your phone?

If you have time, we recommend that you visit a previously posted article regarding this issue. We know that you may be contemplating on replacing your phone with a new one in the near future but the tips that you may gather from that simple guide can be useful in extending the life of your phone’s battery.

Problem #2: Galaxy S5 manual update to Lollipop

I tried to update my AT&T S5, and it appeared to download successfully. It even went as far as asking permission to restart my phone. After pressing “restart”, the phone began to reboot. A text of small blue text  appeared in the top right of the screen. The AT&T logo appears, and a percentage completion scale appears at the bottom of the screen, and says 0%, then says “UPDATE FAILED”. I am unable to check for updates again for another 24 hours in the “ABOUT DEVICE” tab. I hear that the install can be forced thru “ROM” but I’m not able to do that without a step by step tutorial. If you could help me get the new 5.1v onto my phone I would appreciate it. — Jeff

Solution: Hi Jeff. If you want to manually update Android, you have to use a few tools to accomplish it. These tools include a working computer, Odin program, Samsung Kies program, and USB cable.

We haven’t written a step-by-step guide on the matter at this time so we recommend that you use Google instead to look for sites that offer tutorials for this procedure. One of the important things to remember when manually installing a ROM is to ensure that you are using the correct firmware version. In your case, you have to download and use an AT&T Android Lollipop version (UCU3BOC4) instead of others (like Verizon’s VRU1BOA8 or T-Mobile’s UVU1DOB1, etc).

Important: Manually flashing a ROM to your S5 runs the risk of temporarily or permanently damaging the phone (normally called bricking). Do it at your own risk.

Problem #3: Data recovery on a Galaxy S5 that won’t boot

Hello and thank you for all the work you do to help us with our Android devices.

My daughter-in-law’s S5 won’t boot beyond the Verizon screen. I’ve been looking for a way to get her data from it before the Verizon store replaces it. (At least they said they would because it was less than a year old when it began behaving this way.) But, she doesn’t want to lose her data, especially the photos, as they record the last year of her daughter’s life. (She’s 2.) Unfortunately, she didn’t have the camera’s setting set to auto save to the external SD card, nor did she backup to another service or device.

I’ve read your article, How To Fix Boot Up, Battery, Power Problems on Samsung Galaxy S5 [Part 1], and followed the directions regarding clearing the cache. Unfortunately, that wasn’t a working solution. So, before I reset it (or we just despaired and took it back to Verizon) I wanted to inquire of you regarding salvaging any of the data. I know your answer may be, “That’s impossible.” But my motto had always been, “It never hurts to ask.”

So, I’m asking, do you know of any way to salvage the data from a phone in this state? I don’t believe that it was displaying any a-typical behavior prior to  behaving in this manner. As far as I know, she had used it till the battery power ran out and it died. Then she plugged it in to charge and the next morning, when she turned it on it wouldn’t boot beyond the Verizon page. Sorry I don’t have more info for you to work with. Thanks. — Jenelle

P.S. Upon reading a couple of your other articles related to this issue I attempted to restart the phone in Safe Mode and the result was still the same. It didn’t behave any differently; It wouldn’t boot beyond the Verizon screen.

And, where will I see the response to my inquiry?

Solution: Hi Jenelle. If the phone no longer boots up normally and you did not install a custom recovery software like TWRP or clockworkmod on it, we don’t think there’s any other way to recover those files. If you did not root the S5 before, then most probably it is still running the stock recovery software, which does not offer any way to recover personal data stuck inside the phone’s memory.

There are some online sites that claim to offer recovery services but many of them are scams. Your concern is similar to this case that we published before. Try to check if the online sites mentioned in this post can help you recover the data.
