Samsung Galaxy S5's Ultra Power Saving Mode is put to the test

Samsung Galaxy S5's Ultra Power Saving Mode is put to the test
If you've seen the recent commercial for the Samsung Galaxy S5, you know how proud the manufacturer is of its Ultra Power Saving Mode. By going into this mode, the phone turns the screen from color to black and white, using a "simplified greyscale" theme. It also limits the number of apps that can be used. With 10% battery life remaining, this setting will give a Galaxy S5 user 24 hours of standby time. 

Samsung decided to charge up the 2800mAh battery on a Samsung Galaxy S5, and take it on a cross-country road trip to see how far it could go without charging. Keep in mind that the Ultra Power Saving Mode is turned on right from the start, and is turned off from time to time in order to enable some apps.

Leaving New York City at 100% battery life, the Galaxy S5 was at 80% by the time it hit Nashville. Did the Galaxy S5 jump on stage at the Grand Ole Opry and wow the crowd by playing a selection of country tunes? No, it did not. But the phone did make it to Seminole, Oklahoma on day 3, with 73% of its battery life remaining. By day four in Amarillo, Texas, there was 51% battery life left.

Could the phone make it from the East Coast to the West Coast without a charge? In Las Vegas, the indicator read 17%. When the phone reached Venice, it had 7% battery life remaining. According to Samsung, the phone went 3504 miles and 7 days without needing to be charged. Of course, this is hardly typical use. By turning the Ultra Power Saving Mode on, most apps could not be used. And let's face it, if you were on a road trip and sitting in the passenger seat, you'd have your phone running social media non-stop, and you'd probably watch a movie or two on Netflix. On this road trip, 119 pictures were snapped, 86 texts were sent and 4 minutes of video were shot.

While this might have been an interesting experiment, in no way is this indicative of real-life. And we should point out that the HTC One (M8) has its own Extreme Power Saving Mode which came out of the box on international units, and was added via updates to all U.S. models except for those owned by Verizon customers.

If it was a rooted handset, with voltage settings decreased, it would've still have 35% left. 3200mah instead of 2800mah, should've came standard.

I swapped my 2,800mah battery for a Japanese made 3,800mah battery in my Samsung Galaxy S5 Plus!

Simple do a factory reset keep the apps installed down to only what you use often disable apps that you can not uninstall so you always have 2GB free of internal storage and save photos and download to sd card this can be done via phone settings as well as in most apps! Grace UI/UX & now Samsung Experience (No longer Touchwiz!) feels different looks different and is very fast and responsive both on my S8+ & my mum's A7 2017 they have rebuilt it from scratch and it seems to work great now compared to the slow, ugly and buggy TouchWiz found on Pre-Note 7 devices! Funny thing is that my Mum's A7 is built for long battery life so has power efficient SoC even so the new UI/UX works fast and smooth even on a device that sacrifices power/performance for very long battery life (Second best battery life using a standard sized battery after the Moto Z Play witch beats the A7 buy a little over an hour while both are in normal power usage mode!) In short do not dismiss new Samsung phones because of Touchwiz anymore as the new UI is a different to the old one as the S6 was to the S5 in external looks and materials!

I just tried this power saving mode last night and it works well but the 10% was over in 2 hours of of heavy use. I thought it would last longer.

It is to save power (Ultra Power Saving Mode!) if you use it heavily there is only so much any OS, Power Saving Mode Software or SoC can do to increase the battery life over a certain point! basically the point of UPSM is to allow you to make and receive calls and text in emergencies when you power is low, Not to allow you to use facebook for 6 more hours for example! Try a Moto Z Play (2016) or a Samsung A7 (2017) for phones with the best battery life in the world without having to cram huge batteries into the phones like 1+ has to do! * BTW The A7 while only slightly worse than the Z Play for battery life features IP68 rating and 2 year warranty!​7-2017-scores-amazing-on-our-battery-life-test_id9​1838

Have to admit, this idea of having a black and white mode power saver was a pure Samsung innovation.

Haters gonna hate..... Unless you have a Huawei Ascend Mate 2 I don't think your phone really would stand up to a cross country test.... Let's get real.

Android and Open Source are the Future. it doesn't lock you down to one company. it's not a walled garden like apple. it's an open palm vs a closed fist. you pay half or less for the hardware than apple's hardware. the apple premium 'tax' is for bragging rights and advertising costs. the truth is actually a bit different than the apple marketing machine will lead you to believe. there is a reason why apple has more cash in the bank than any other U.S. company. check your wallets.

ummm...what? the iphone is junk. just look at the specs! Apple bragged about how now it has a dual core. so what, Android phones have quad cores and have for some time. Apple consistently releases outdated tech, stolen interfaces that they pass off as their inventions and then they sensationalize it like its the newest and best thing in the world. the worst thing about it is that people like this guy keep spewing that word vomit. When you buy a smartphone, be an informed consumer and know what you are buying. Dual core iPhone vs quad core Android. hrmmmm.... 16gig iphone vs 16gig plus 64gig external storage Android. hrmmmm.... closed source and restricted to only what apple says you can have or do iPhone vs open source make your phone do whatever you want Android.... hrmmm.... its an easy choice for someone who doesn't just buy a phone to try to look cool to their friends.

Wow you sound really butthurt, why does it matter to you what other people buy, apples dual core processor is custom made and every core performs as a single core better than the 801, now that is in single thread not multithread which is a different story, but you can't tell the difference in real life performance, I have used the S5 and I'm still surprised not to the hardware's fault but to the software that performance still stutters from time to time, the more gimmicks they add the more it bugs down the system as well it takes more internal storage available. Yes expandable store is good but there is a reason google wants to move away from it, on their nexus devices is because is unreliable, they tend to fail a lot.

Arte, this is unnecessary... He's not bashing Samsung - he's stating that 24 hours on a 10% battery is only possible if you don't use the phone (or just a little). Samsung is trying to convince (with their ad or this stunt) that their phone is capable of that, but does not outline that the use is limited, very limited. I like this feature, but lets not make a gold mine out of mole hill...

Where is the 32gb Galaxy S5? Where is it? I have the money ready. I know what phone I want. Samsung must have planned a 32gb version. Why isn't it out yet? This has nothing to do with the articles but I must reiterate that my money is ready. Just release it already. Stop playing games. 16gb isn't enough internal storage. Samsung! Can you hear me. I won't just buy the phone. I'll buy an extra battery and a micro sd card from you. Just release the 32gb S5 and accept my credit card. That simple. 32gb is all I want. Not asking for a miracle. RELEASE THE 32GB NOW!!!!!
