Logitech G602 battery life

My Logitech G602 mouse was delivered to me on April 4, so it is 2 months and a week to-date. So how many times did I have to change the batteries?

Zero times!

The battery life of this “wireless” mouse is downright amazing. I’m still using the original batteries that came bundled with the mouse. According to the Logitech Gaming Software (the screenshot above), there is about half of the battery life still left.

I have to confess though, I didn’t have much time to play games in the past few days. That privilege was available in the weekend, and even then when the baby was sleeping. As a result, the mouse was mostly in the “Endurance” state, not “Performance” state. But still…it’s admirable. I was expecting to change the batteries at least once every two weeks.

[Article] iPhone 5S is awesome.

Well, at least compared to my old iPhone it is million times better. I'm sure people with the iPhone 5 won't notice the difference.  Or the hardcore Android guys or Windows Phone guys. I love Windows Phone, but I cannot get one in Japan, so I have no choice.

The biggest improvements I see are in the areas of UI fluidity, app launch speeds, network speed and battery life. Screen is largeer but it is not that noticeable. 

The A7 processor in the iPhone 5S is almost 4 times faster than the iPhone 4S's A5 processor. I'm sure the improved GPU is helping with the fluidity of the UI animations  I thought the animations of iOS 7 were so slow but I don't feel that with the iPhone 5S. I don't play games on the phone so I really cannot comment on the gaming performance. However, I'm sure I will get used to the speed and start feeling that this is no big deal after all. That happened with the iPhone 4S as well.

The biggest difference I see is with network speeds. LTE is way better than 3G - especially 3G on SoftBank because it SUCKED. With LTE, now I can stream YouTube, webpages open super fast and download apps quickly. For example, the Coursera courses page took ages to open on my 4S, but it opens within a couple of seconds on the 5S. On the day that I bought the 5S, I downloaded almost 700MB of apps on the way home from work, on the train. I wonder if that 7.5GB limit won't be sufficient for a month. It's possible that the amazing LTE speeds that I see are because most people are still on 3G and that the network is not congested. Or it could be a feature of LTE. I have not looked into LTE, not even a bit. (I should!) The quality/speed might change in the near future though because of all the people upgrading from their iPhone 4S to iPhone 5S.

Then the battery life - it's way better than I expected. If I leave home with a 100% charge, I can return with a 25-30% charge remaining. On the 4S, maybe because of the terrible 3G speeds, I couldn't get by a day with a full charge. Because of that, I had to charge the phone at work almost every day. It could be because its battery was worn out. But it could also be because LTE is so fast that it can go into idle state quickly. Besides, the iPhone 5S has a much bigger battery that the iPhone 4S. However, if I drain the battery, I won't have a charging cable with me. I wonder if the cheap Chinese rip-offs can at least charge the phone. I don't want to access the content of the phone from the PC.

Other than that, the finger print reader works really quickly. I thought you would get a lot of false positives with it but that is not the case. But I'm still not used to the whole idea of it, and I only remember I can use the finger almost half way through to entering the passcode lock. 

I haven't had time to use the camera yet. Hey, I am not a photo guy. I don't think it will be as good as the PureView camera in the Nokia Lumia 1020, but since they say it is better than the previous generation, which was even better than the 4S's, I'd take that as a "vastly improved camera". Hehe.

[Review] Dell Latitude 10 Essentials Windows 8 tablet user review–part 3: the performance, the camera and battery life

This is the part 3 of the Dell Latitude 10 Essentials Windows 8 tablet user review. This one is about the performance, the camera and battery life.

Note: If you missed the part 1 and 2, click on the following links to read them.

Part 1: Ease of holding the tablet and look & feel

Part 2: Usability

OK, let’s get on with this section then.

Performance

If you want to find out how measurably fast the tablet is, read this review. I will not go into those tests. I will only talk about how I feel, together with Windows 8.

1) CPU

I am a guy that loves fast computers. This tablet definitely isn't fast. That’s mostly due to the Atom Clovertrail 1.8GHz dual core/hyper threaded CPU in there. The specs wise, it doesn’t seem slow, but Clovertrail is an in-order executed CPU, which makes it slow compared to Core series CPUs.  But I knew that before I bought it.

There was no choice, to be honest. ARM doesn't support full version of Windows 8 and Intel Core series CPUs have terrible battery life, need active cooling and all that adds weight. So we all have to put up with the slowness of the Atom chips. Hopefully Baytrail will fix it.

2) Storage

Anyways, the CPU doesn't seem to be the only thing that is slow in this tablet. The storage medium is eMMC which is solid state alright, but doesn't have the raw speed of an SSD. It's pretty slow, just like a USB flash drive.

3) The OS itself

But Windows 8 modern apps are slow to launch anyways. The video app for example takes about 5 seconds to load a video for the first time. The Windows Store is terrible. It is slow and needs a lot of user interactions to get the smallest thing done.

4) Wi-Fi

Downloads are not so fast. Wi-Fi browsing performance is comparable to my iPhone 4S, sometimes even slower. I was expecting more. The current generation devices have better Wi-Fi performance than iPhone 4S.

The Camera

The camera on a tablet doesn’t make much sense and people taking photos with a tablet look like idiots. But nevertheless, some people would like to see how the camera performs. I captured a video and took some photos with it.

Battery life

I haven't measure the battery life accurately but according to the proper reviews, the battery seems to hold for about 8-10hrs. That's good and you should not expect nothing less from a CPU this slow. In other words, you won't have to worry about the battery life.
