Enterprise (802.1x) WiFi causing excessive battery drain?

在过去的一周里，意识到WiFi在工作（使用802.1x auth）一直在疯狂地排出我的电池。

这里有一些我在过去几天服用的统计数据：

  Case   Connection       Duration     Battery left  A      802.1x Wifi      ~10hrs          0%  B      3G               ~17hrs         46%  C      WPA2 Wifi        ~1d 11hrs      34%

在所有三种情况下，用法很亮：偶尔检查电子邮件，短信或两个，短手机等如果有的话，可能在B＆amp的情况下使用手机更多。

奇怪的是这个疯狂的电池排水管只在过去一周左右发生 - 在连接到802.1x wifi时〜15小时后常用于20％。

是否有人知道为什么企业/ 802.1x WiFi导致显着的电池排水管？

英文原文

In the past week, realised that WiFi at work (using 802.1x auth) has been draining my battery like crazy.

Here are some stats I took over the past few days:

Case   Connection       Duration     Battery left  A      802.1x Wifi      ~10hrs          0%  B      3G               ~17hrs         46%  C      WPA2 Wifi        ~1d 11hrs      34%

In all three cases, usage was light: occasional checking of email, sms or two, short phone call etc. If anything, probably used the phone more in case B&C - played some light games.

The odd thing is this crazy battery drain has only been happening in the past week or so - used to be at 20% after ~15hours when connected to 802.1x Wifi.

Does anyone know why Enterprise/802.1x WiFi is causing significant battery drain?

告诉我们有关您的设备的信息会很高兴。我想所有这些问题都是特定于设备的（或特定设备的ROM）。我对设备三星Galaxy S2和华为G300的经验表明，802.1X和WPA2-PSK的电池使用情况下没有那么大。〜Jiri nestor11 2013-03-03 11:43:48Z, License: CC BY-SA 3.0

详细信息添加了。如果它与ROM /手机有关，因此我在一个月内运行这种配置，并且电池排水问题只能从过去一周左右开始。 pyko 2013-03-03 11:49:36Z, License: CC BY-SA 3.0

当问题开始发生此问题时，您是否安装了任何特殊的东西？你能粘贴电池统计的屏幕吗？恕我直言，我发现了基于果冻Bean 4.2的许多自定义ROM有严重的电池漏极问题。 nestor11 2013-03-03 17:14:54Z, License: CC BY-SA 3.0

使用链接到屏幕截止的更新问题。没有应用程序/没有特别跳到思想 - 在那个时间范围内可能升级了SWIFTKEY。令人费解的事情是无论它是什么，它绝对只是影响企业/ 802.1x WiFi（并且只在近几周内 - 这可能不是ROM） pyko 2013-03-04 10:34:06Z, License: CC BY-SA 3.0

我已经在我自己的网络上确认，802.1x导致电池过多。我有2个SSID的AP。一个是802.1x，一个是开放的。我在802.1倍上耗尽6％和小时，开放2％。不确定它是否会对半径进行身份验证或导致问题的原因。我很乐意为某人解决这个问题，因为802.1x有这么多其他好处。 2015-02-13 00:53:51Z, License: CC BY-SA 3.0

it would be nice to tell us info about your device. I suppose all those problems are device specific (or ROM for specific device). My experiences with device Samsung Galaxy S2 and Huawei G300 shows that there is not that much big difference between battery usage on 802.1x and WPA2-PSK. ~ Jiri nestor11 2013-03-03 11:43:48Z, License: CC BY-SA 3.0

Details added. Not convinced if it has to do with ROM/phone, since I was running this configuration for over a month, and battery draining problem is only from the past week or so pyko 2013-03-03 11:49:36Z, License: CC BY-SA 3.0

Have you installed anything special when this problem started to occur? Could you paste a screen of your battery stats? Imho, I found out that many custom ROMs based on Jelly Bean 4.2 have serious problems with battery drain nestor11 2013-03-03 17:14:54Z, License: CC BY-SA 3.0

Updated question with link to screenshots. No apps/nothing special that jumps to mind - possibly upgraded SwiftKey around that timeframe. Puzzling thing is whatever it is, it is definitely only affecting Enterprise/802.1x WiFi (and only in the recent few weeks - so likely not ROM) pyko 2013-03-04 10:34:06Z, License: CC BY-SA 3.0

I have confirmed on my own network that 802.1x causes excessive battery drain. I have AP's with 2 SSID's. One is 802.1x and one is OPEN. I get 6% and hour drain on 802.1x and 2% on OPEN. Not sure if it keeps authenticating to the RADIUS or what is causing the issue. I would LOVE for someone to resolve this as 802.1x has so many other benefits 2015-02-13 00:53:51Z, License: CC BY-SA 3.0
